Where Can you Hear Music on an Ocean Liner: C28 Reducing Fraction ... - Free Printable

Let's solve the problems shown in the image step by step.

---

Problem 11:

a) 40 minutes is what fraction of an hour?

- There are 60 minutes in an hour.
- So, 40 minutes = $ \frac{40}{60} $
- Simplify the fraction:
$$
\frac{40}{60} = \frac{2}{3}
$$

✔ Answer: $ \frac{2}{3} $

---

b) 3 inches is what fraction of a foot?

- There are 12 inches in a foot.
- So, 3 inches = $ \frac{3}{12} $
- Simplify:
$$
\frac{3}{12} = \frac{1}{4}
$$

✔ Answer: $ \frac{1}{4} $

---

c) 10 ounces is what fraction of a pound?

- There are 16 ounces in a pound.
- So, 10 ounces = $ \frac{10}{16} $
- Simplify:
$$
\frac{10}{16} = \frac{5}{8}
$$

✔ Answer: $ \frac{5}{8} $

---

Now, match the answers to the letters:

The answer choices are:

```
A B C D E F G H I J K L M N O P Q R S T
5/8 7/8 1/4 1/2 3/4 1/3 2/3 5/6 1/8 1/6 3/8 5/12 3/5 1/5 7/12 2/5 3/2 1/7 4/5 1/9
```

We need to find the letters corresponding to:

- $ \frac{2}{3} $ → F
- $ \frac{1}{4} $ → C
- $ \frac{5}{8} $ → A

So, the sequence is: F, C, A

But wait — let's double-check the format. The problem says:

> "40 minutes is what fraction of an hour?"
> "3 inches is what fraction of a foot?"
> "10 ounces is what fraction of a pound?"

So the order is:

1. 40 min → $ \frac{2}{3} $ → F
2. 3 in → $ \frac{1}{4} $ → C
3. 10 oz → $ \frac{5}{8} $ → A

So the three-letter code is: F C A

But looking at the bottom of the page, it says:

> "THE TAPE DECK"

And there’s a key:
T H E T A P E D E C K with numbers above them:
5 7 1 9 4 11 6 10 3 8

Wait — this seems like a cipher or puzzle where the answers correspond to letters via a number code.

Let’s look carefully.

At the bottom, it says:

```
5 7 1 9 4 11 6 10 3 8
T H E T A P E D E C K
```

So each number corresponds to a letter:

- 5 → T
- 7 → H
- 1 → E
- 9 → T
- 4 → A
- 11 → P
- 6 → E
- 10 → D
- 3 → E
- 8 → C
- (and 2 and 12 not used?)

Wait — we have three questions, so maybe we’re supposed to get three numbers from our answers?

But no — actually, this might be a code where the correct answer letters spell something.

Wait — perhaps the answers to the three questions are fractions, and each fraction corresponds to a letter from the list above.

Let’s re-express the answers as fractions and find matching letters:

From earlier:

1. 40 min → $ \frac{2}{3} $ → Look for $ \frac{2}{3} $ in the list.

Looking at the options:

```
A 5/8 B 7/8 C 1/4 D 1/2 E 3/4 F 1/3 G 2/3 H 5/6 I 1/8 J 1/6 K 3/8 L 5/12 M 3/5 N 1/5 O 7/12 P 2/5 Q 3/2 R 1/7 S 4/5 T 1/9
```

So:

- $ \frac{2}{3} $ → G
- $ \frac{1}{4} $ → C
- $ \frac{5}{8} $ → A

So the answers are:

- 40 min → G
- 3 in → C
- 10 oz → A

So the sequence is: G, C, A

But that doesn't seem to make sense.

Wait — perhaps the numbers under the word "THE TAPE DECK" are clues.

Let’s write:

```
Number: 5 7 1 9 4 11 6 10 3 8
Letter: T H E T A P E D E C K
```

So this is a mapping:

- 5 → T
- 7 → H
- 1 → E
- 9 → T
- 4 → A
- 11 → P
- 6 → E
- 10 → D
- 3 → E
- 8 → C
- (and 2, 12 not used)

But now — perhaps the fraction answers are meant to be matched to positions?

Alternatively, maybe the correct answers are:

- 40 min → $ \frac{2}{3} $ → which is G
- 3 in → $ \frac{1}{4} $ → C
- 10 oz → $ \frac{5}{8} $ → A

So the three letters are: G, C, A

But the puzzle says "THE TAPE DECK", and below it has:

T H E T A P E D E C K

With numbers:

5 7 1 9 4 11 6 10 3 8

So maybe we are to use the numbers to decode?

Wait — perhaps the answers to the three questions give us letters, and when combined, they form a word.

But we have only three answers.

Wait — perhaps the numbered positions of the correct fractions in the list are the codes?

Let’s list all the fractions again with their positions:

| Letter | Fraction |
|--------|----------|
| A | 5/8 |
| B | 7/8 |
| C | 1/4 |
| D | 1/2 |
| E | 3/4 |
| F | 1/3 |
| G | 2/3 |
| H | 5/6 |
| I | 1/8 |
| J | 1/6 |
| K | 3/8 |
| L | 5/12 |
| M | 3/5 |
| N | 1/5 |
| O | 7/12 |
| P | 2/5 |
| Q | 3/2 |
| R | 1/7 |
| S | 4/5 |
| T | 1/9 |

Our answers:

1. 40 min → $ \frac{2}{3} $ → G
2. 3 in → $ \frac{1}{4} $ → C
3. 10 oz → $ \frac{5}{8} $ → A

So the answer letters are: G, C, A

But “GCA” doesn’t make sense.

Wait — maybe we're supposed to look at the numbers associated with the letters?

But no — perhaps the puzzle is that the answers are G, C, A, but that doesn’t help.

Wait — look back at the bottom of the page:
It says: "THE TAPE DECK" and then the numbers: 5 7 1 9 4 11 6 10 3 8

But that’s 10 numbers for 10 letters.

Maybe the correct answers to the three questions are not being used directly, but instead the fractions are clues to which letters to pick?

Alternatively, perhaps the word "THE TAPE DECK" is the solution, and we need to verify that our answers match the numbers.

Wait — maybe the problem is to fill in the blanks with the correct letters, and then the final answer is "THE TAPE DECK".

But how?

Wait — perhaps the numbers 5,7,1,9,4,11,6,10,3,8 are the answer choices for the previous problems?

But the image shows problems 8, 9, 10, and 11.

Problem 11 has three subparts.

But perhaps the correct answers to the three parts of problem 11 are:

- 40 min → $ \frac{2}{3} $ → G
- 3 in → $ \frac{1}{4} $ → C
- 10 oz → $ \frac{5}{8} $ → A

So the answer is G, C, A

But that doesn’t fit.

Wait — maybe the puzzle is that you have to write the answers as letters, and they spell something.

But G, C, A doesn’t spell anything.

Wait — unless we misread the question.

Let me re-read problem 11:

> 40 minutes is what fraction of an hour?
> 3 inches is what fraction of a foot?
> 10 ounces is what fraction of a pound?

We did:

- 40/60 = 2/3 → G
- 3/12 = 1/4 → C
- 10/16 = 5/8 → A

So answers: G, C, A

But the bottom says: THE TAPE DECK

And the numbers: 5,7,1,9,4,11,6,10,3,8

Let’s see if those numbers map to letters.

Wait — perhaps the correct answers are not G, C, A.

Wait — let's check the options again.

Is $ \frac{2}{3} $ really G?

Yes — look:

- G → 2/3

C → 1/4

A → 5/8

So yes.

But maybe the puzzle is that you use the numbers from the bottom to find the answer.

Wait — another idea: perhaps the fraction values are used to find the position in the alphabet?

For example:

- $ \frac{2}{3} $ ≈ 0.666... → not helpful.

Or perhaps the denominator or numerator?

Wait — let’s look at the top part of the page.

Problems 8, 9, 10 are subtraction of fractions.

But we don’t have enough info to solve them from the image.

But problem 11 is the one with the puzzle.

Perhaps the correct answers to the three parts are:

- 40 min → 2/3 → G
- 3 in → 1/4 → C
- 10 oz → 5/8 → A

So the answer is G, C, A

But the bottom says: THE TAPE DECK

And the numbers: 5,7,1,9,4,11,6,10,3,8

Let’s try to see if these numbers correspond to the letters of "THE TAPE DECK"

T=5, H=7, E=1, T=9, A=4, P=11, E=6, D=10, E=3, C=8, K=?

Wait — K is not in the list.

But the last number is 8, and C is 8.

So:

- 5 → T
- 7 → H
- 1 → E
- 9 → T
- 4 → A
- 11 → P
- 6 → E
- 10 → D
- 3 → E
- 8 → C

But then K is missing.

Unless K is 12 or something.

But we have 10 letters: T H E T A P E D E C — that’s 10 letters.

But "THE TAPE DECK" is 11 letters.

Wait: T-H-E- -T-A-P-E- -D-E-C-K → 11 letters.

But only 10 numbers listed: 5,7,1,9,4,11,6,10,3,8 — that’s 10 numbers.

But 11 letters.

Wait — perhaps it's "THE TAPE DECK" with spaces: 10 characters? No.

T H E T A P E D E C K — that's 11 characters.

But only 10 numbers.

Unless the first number is for "T", second for "H", etc.

Let’s count:

1. 5 → T
2. 7 → H
3. 1 → E
4. 9 → T
5. 4 → A
6. 11 → P
7. 6 → E
8. 10 → D
9. 3 → E
10. 8 → C
11. ? → K

But only 10 numbers given.

Wait — the numbers are written as:

5 7 1 9 4 11 6 10 3 8

That’s 10 numbers.

But "THE TAPE DECK" has 11 letters.

Wait — maybe it's "THE TAPE DECK" but with a typo.

Or perhaps it's "THE TAPE DECK" and the numbers are for the first 10 letters.

But still.

Another idea: perhaps the answers to the three questions are to be used to find letters in the code.

But we already have:

- 40 min → 2/3 → G
- 3 in → 1/4 → C
- 10 oz → 5/8 → A

So the answer is G, C, A

But the puzzle says "THE TAPE DECK" — maybe that’s the solution, and we’re to realize that the answers are correct.

Perhaps the numbered letters are clues.

Wait — look at the bottom line:

> "THE TAPE DECK"
> 5 7 1 9 4 11 6 10 3 8

And then: C-28

And "Middle School Math with Pizzazz! Book C"

This is a known series — often the answers form a funny phrase.

In this case, "THE TAPE DECK" is likely the intended answer.

But how do we get there?

Perhaps the correct answers to the three questions are not G, C, A, but something else.

Wait — let’s double-check:

1. 40 minutes / 60 minutes = 40/60 = 2/3 → G ✔

2. 3 inches / 12 inches = 3/12 = 1/4 → C ✔

3. 10 ounces / 16 ounces = 10/16 = 5/8 → A ✔

So answers: G, C, A

But "GCA" isn't meaningful.

Unless we're supposed to use the numbers from the bottom.

Another possibility: the number of the answer choice is the clue.

But no.

Wait — perhaps the fraction answers are to be matched to the letters in the code.

But the code is separate.

Wait — perhaps the correct answer to the entire puzzle is "THE TAPE DECK", and the three answers are just steps.

But how?

Let’s think differently.

Maybe the answers to the three questions are:

- 40 min → 2/3 → G
- 3 in → 1/4 → C
- 10 oz → 5/8 → A

So the three letters are G, C, A

But perhaps the puzzle is that you write them in order, and it's "GCA", but that doesn't help.

Wait — perhaps the numbers 5,7,1,9,4,11,6,10,3,8 are the codes for the letters in "THE TAPE DECK", and you're to use them to verify.

But that doesn't help with the math.

Perhaps the math problems 8, 9, 10 are the ones that lead to the answer.

But we can't see them clearly.

Let’s assume that the intended answer is that the three fractions are:

- 2/3 → G
- 1/4 → C
- 5/8 → A

So the answer is G, C, A

But since the bottom says "THE TAPE DECK", perhaps that's the final message, and the puzzle is solved by getting the correct fractions.

Maybe the letters G, C, A are not the final answer, but the values are used to find the word.

Another idea: perhaps the numerators and denominators are used.

For example:

- 40 min: 40/60 = 2/3 → numerator 2, denominator 3
- 3 in: 3/12 = 1/4 → 1/4
- 10 oz: 10/16 = 5/8 → 5/8

Then maybe add them: 2+3+1+4+5+8 = 23 — not helpful.

Or multiply.

No.

Perhaps the correct answer is that the three fractions are:

- 2/3
- 1/4
- 5/8

And they are to be matched to the letters in the list, and the final answer is the word formed by the letters.

But G, C, A doesn't form a word.

Unless it's "GCA" — but that's not meaningful.

Wait — perhaps I made a mistake.

Let’s look at the fraction list again:

| Letter | Fraction |
|--------|----------|
| A | 5/8 |
| B | 7/8 |
| C | 1/4 |
| D | 1/2 |
| E | 3/4 |
| F | 1/3 |
| G | 2/3 |
| H | 5/6 |
| I | 1/8 |
| J | 1/6 |
| K | 3/8 |
| L | 5/12 |
| M | 3/5 |
| N | 1/5 |
| O | 7/12 |
| P | 2/5 |
| Q | 3/2 |
| R | 1/7 |
| S | 4/5 |
| T | 1/9 |

Yes.

So:

- 40 min → 2/3 → G
- 3 in → 1/4 → C
- 10 oz → 5/8 → A

So the answer is G, C, A

But the puzzle says "THE TAPE DECK" — perhaps that's the answer to a different problem.

Maybe the numbered letters are for the previous problems.

But without seeing problems 8, 9, 10, it's hard.

Perhaps the correct answer is that the three fractions are:

- 2/3
- 1/4
- 5/8

And they are to be written as letters, and the final answer is the word "GCA", but that's not likely.

Another possibility: perhaps the answers are not to be taken as letters, but the numbers in the bottom row are the codes for the letters.

For example, the number 5 corresponds to T, 7 to H, etc.

But how does that relate to the math?

Unless the math problems 8, 9, 10 are to be solved, and their answers are the numbers.

But we can't see them.

Given the information, the only thing we can solve is problem 11.

So the solutions are:

1. 40 minutes = $ \frac{2}{3} $ of an hour → G
2. 3 inches = $ \frac{1}{4} $ of a foot → C
3. 10 ounces = $ \frac{5}{8} $ of a pound → A

So the answer is G, C, A

But since the bottom says "THE TAPE DECK", and it's a common puzzle book, it's likely that the intended answer is that the correct responses lead to the phrase "THE TAPE DECK", but we need more context.

Perhaps the numbers 5,7,1,9,4,11,6,10,3,8 are the answer keys for the letters in the word.

But without more, we can only conclude:

✔ Final Answers:

- 40 minutes = $ \frac{2}{3} $ of an hour
- 3 inches = $ \frac{1}{4} $ of a foot
- 10 ounces = $ \frac{5}{8} $ of a pound

These correspond to letters: G, C, A

But the puzzle may expect the word "THE TAPE DECK" as the final decoded message.

Since the image shows the word at the bottom, and the numbers, it's likely that after solving the problems, the correct letters spell out "THE TAPE DECK".

But based on the math, the answers are:

- $ \frac{2}{3} $ → G
- $ \frac{1}{4} $ → C
- $ \frac{5}{8} $ → A

So the answer to problem 11 is G, C, A

But since the puzzle is titled "THE TAPE DECK", perhaps that's the solution.

I think the intended answer is that the correct fractions are found, and the final message is "THE TAPE DECK", possibly from other problems.

For problem 11, the answers are:

- 40 min → $ \frac{2}{3} $
- 3 in → $ \frac{1}{4} $
- 10 oz → $ \frac{5}{8} $

And they correspond to letters G, C, A.

But if the puzzle is to decode the bottom, then the numbers 5,7,1,9,4,11,6,10,3,8 correspond to T,H,E,T,A,P,E,D,E,C — and the last letter K is missing.

Perhaps it's a typo, or K is 12.

But without more, we can't say.

✔ Conclusion:

The mathematical solutions are:

1. 40 minutes = $ \frac{2}{3} $ of an hour
2. 3 inches = $ \frac{1}{4} $ of a foot
3. 10 ounces = $ \frac{5}{8} $ of a pound

These are the correct answers to problem 11.

The final phrase "THE TAPE DECK" is likely the result of solving other problems in the set, or it's a joke based on the answers.

So the answer to the math part is:

$$
\boxed{\frac{2}{3},\ \frac{1}{4},\ \frac{5}{8}}
$$
