Step-by-step solution for: Printable primary math worksheet for math grades 1 to 6 based on ...
Explanation:
We need to find the better buy in each pair — that means the option with the lower unit price (price per item, per kilogram, per liter, etc.).
To do this, we calculate the unit price for each option and compare.
Let’s go row by row:
---
1. Footballs
- 3 footballs for $4.50 → unit price = $4.50 ÷ 3 = $1.50 each
- 5 footballs for $8 → unit price = $8 ÷ 5 = $1.60 each
✔ Better buy: 3 footballs for $4.50
---
2. Calculators
- 5 calculators for $140 → $140 ÷ 5 = $28 each
- 9 calculators for $243 → $243 ÷ 9 = $27 each
✔ Better buy: 9 calculators for $243
---
3. Apples
- 2 apples for $0.80 → $0.80 ÷ 2 = $0.40 each
- 6 apples for $2.10 → $2.10 ÷ 6 = $0.35 each
✔ Better buy: 6 apples for $2.10
---
4. Sugar
- 5 kg for $12 → $12 ÷ 5 = $2.40/kg
- 12 kg for $30 → $30 ÷ 12 = $2.50/kg
✔ Better buy: 5 kg for $12
---
5. Pencils
- 100 pencils for $45 → $45 ÷ 100 = $0.45 each
- 80 pencils for $32 → $32 ÷ 80 = $0.40 each
✔ Better buy: 80 pencils for $32
---
6. Books
- 10 books for $150 → $150 ÷ 10 = $15 each
- 16 books for $232 → $232 ÷ 16 = $14.50 each
✔ Better buy: 16 books for $232
---
7. Milk
- 17 L for $51 → $51 ÷ 17 = $3.00/L
- 230 L for $736 → $736 ÷ 230 = let’s compute:
230 × 3 = 690
736 − 690 = 46
So $736 ÷ 230 = 3 + 46/230 = 3 + 0.2 = $3.20/L
✔ Better buy: 17 liters for $51
---
8. Motorbikes
- 3 motorbikes for $1,650 → $1,650 ÷ 3 = $550 each
- 7 motorbikes for $3,675 → $3,675 ÷ 7 = let’s compute:
7 × 500 = 3,500
3,675 − 3,500 = 175
175 ÷ 7 = 25
So total = 500 + 25 = $525 each
✔ Better buy: 7 motorbikes for $3,675
---
9. Ice-creams
- 2 ice-creams for $0.95 → $0.95 ÷ 2 = $0.475 each
- 9 ice-creams for $4.05 → $4.05 ÷ 9 = $0.45 each
✔ Better buy: 9 ice-creams for $4.05
---
10. Staplers
- 12 staplers for $30 → $30 ÷ 12 = $2.50 each
- 7 staplers for $16.80 → $16.80 ÷ 7 = let’s compute:
7 × 2 = 14
16.80 − 14 = 2.80
2.80 ÷ 7 = 0.40
So total = 2 + 0.40 = $2.40 each
✔ Better buy: 7 staplers for $16.80
---
11. Chocolate bars
- 3 bars for $1.80 → $1.80 ÷ 3 = $0.60 each
- 15 bars for $13.50 → $13.50 ÷ 15 =
15 × 0.9 = 13.5 → so $0.90 each
✔ Better buy: 3 chocolate bars for $1.80
---
12. Coffee cups
- 24 cups for $36 → $36 ÷ 24 = $1.50 each
- 30 cups for $48 → $48 ÷ 30 = $1.60 each
✔ Better buy: 24 coffee cups for $36
Now, the question says:
> Which is the better buy? What’s its unit price?
But since there are 12 separate comparisons, and no single “final” answer is requested beyond identifying the better buy in each case, the task likely expects us to list all the better buys with their unit prices.
However, looking at standard versions of this worksheet, the expected output is to write the better buy *for each pair*, often in a format like:
- 3 footballs for $4.50 → $1.50 each
- 9 calculators for $243 → $27 each
... and so on.
But since the user only asks to “Solve the problem accurately”, and the instruction says:
> ONLY THEN provide the final answer.
And the format says:
Final Answer: [Provide only the final correct answer]
Given that it's a worksheet with multiple items, and the header says “Unit Price/Better Buys”, the most reasonable interpretation is that the student is to fill in the better buy and its unit price for each row.
But since the output must be *only* the final answer (and not a list), and the problem doesn’t specify which one to pick, I suspect the expectation is to list all the better buys with unit prices — but the instructions say “only the final correct answer”.
Wait — re-reading: The worksheet has blank lines for Name and Score, and then the questions. In classroom practice, students write the better buy (e.g., “3 footballs for $4.50”) and its unit price (e.g., “$1.50 each”) for each.
But since the assistant must output only the Final Answer, and the user hasn’t specified a particular row, the only consistent way is: the problem is to determine the better buy in each of the 12 pairs, and the *correct answers* are:
1. 3 footballs for $4.50 — $1.50
2. 9 calculators for $243 — $27
3. 6 apples for $2.10 — $0.35
4. 5 kg sugar for $12 — $2.40/kg
5. 80 pencils for $32 — $0.40
6. 16 books for $232 — $14.50
7. 17 L milk for $51 — $3.00/L
8. 7 motorbikes for $3,675 — $525
9. 9 ice-creams for $4.05 — $0.45
10. 7 staplers for $16.80 — $2.40
11. 3 chocolate bars for $1.80 — $0.60
12. 24 coffee cups for $36 — $1.50
But the instruction says: Provide only the final correct answer — implying one answer. That suggests maybe the question is misread.
Wait — look again at the top:
> Which is the better buy? What’s its unit price?
It’s repeated for each pair. So the worksheet expects 12 answers.
Since the system requires a single "Final Answer", and the user did not specify a particular row, but the task is clearly a list, the safest approach is to output the better buy and unit price for each, as a clean list — but the rules say *only* the final answer, after reasoning.
Given this is a standard math worksheet, and many online sources show the answer key as a list, I will provide the 12 better buys with unit prices in a compact format, as the final answer.
Final Answer:
1. 3 footballs for $4.50 — $1.50 each
2. 9 calculators for $243 — $27 each
3. 6 apples for $2.10 — $0.35 each
4. 5 kg sugar for $12 — $2.40/kg
5. 80 pencils for $32 — $0.40 each
6. 16 books for $232 — $14.50 each
7. 17 L milk for $51 — $3.00/L
8. 7 motorbikes for $3,675 — $525 each
9. 9 ice-creams for $4.05 — $0.45 each
10. 7 staplers for $16.80 — $2.40 each
11. 3 chocolate bars for $1.80 — $0.60 each
12. 24 coffee cups for $36 — $1.50 each
We need to find the better buy in each pair — that means the option with the lower unit price (price per item, per kilogram, per liter, etc.).
To do this, we calculate the unit price for each option and compare.
Let’s go row by row:
---
1. Footballs
- 3 footballs for $4.50 → unit price = $4.50 ÷ 3 = $1.50 each
- 5 footballs for $8 → unit price = $8 ÷ 5 = $1.60 each
✔ Better buy: 3 footballs for $4.50
---
2. Calculators
- 5 calculators for $140 → $140 ÷ 5 = $28 each
- 9 calculators for $243 → $243 ÷ 9 = $27 each
✔ Better buy: 9 calculators for $243
---
3. Apples
- 2 apples for $0.80 → $0.80 ÷ 2 = $0.40 each
- 6 apples for $2.10 → $2.10 ÷ 6 = $0.35 each
✔ Better buy: 6 apples for $2.10
---
4. Sugar
- 5 kg for $12 → $12 ÷ 5 = $2.40/kg
- 12 kg for $30 → $30 ÷ 12 = $2.50/kg
✔ Better buy: 5 kg for $12
---
5. Pencils
- 100 pencils for $45 → $45 ÷ 100 = $0.45 each
- 80 pencils for $32 → $32 ÷ 80 = $0.40 each
✔ Better buy: 80 pencils for $32
---
6. Books
- 10 books for $150 → $150 ÷ 10 = $15 each
- 16 books for $232 → $232 ÷ 16 = $14.50 each
✔ Better buy: 16 books for $232
---
7. Milk
- 17 L for $51 → $51 ÷ 17 = $3.00/L
- 230 L for $736 → $736 ÷ 230 = let’s compute:
230 × 3 = 690
736 − 690 = 46
So $736 ÷ 230 = 3 + 46/230 = 3 + 0.2 = $3.20/L
✔ Better buy: 17 liters for $51
---
8. Motorbikes
- 3 motorbikes for $1,650 → $1,650 ÷ 3 = $550 each
- 7 motorbikes for $3,675 → $3,675 ÷ 7 = let’s compute:
7 × 500 = 3,500
3,675 − 3,500 = 175
175 ÷ 7 = 25
So total = 500 + 25 = $525 each
✔ Better buy: 7 motorbikes for $3,675
---
9. Ice-creams
- 2 ice-creams for $0.95 → $0.95 ÷ 2 = $0.475 each
- 9 ice-creams for $4.05 → $4.05 ÷ 9 = $0.45 each
✔ Better buy: 9 ice-creams for $4.05
---
10. Staplers
- 12 staplers for $30 → $30 ÷ 12 = $2.50 each
- 7 staplers for $16.80 → $16.80 ÷ 7 = let’s compute:
7 × 2 = 14
16.80 − 14 = 2.80
2.80 ÷ 7 = 0.40
So total = 2 + 0.40 = $2.40 each
✔ Better buy: 7 staplers for $16.80
---
11. Chocolate bars
- 3 bars for $1.80 → $1.80 ÷ 3 = $0.60 each
- 15 bars for $13.50 → $13.50 ÷ 15 =
15 × 0.9 = 13.5 → so $0.90 each
✔ Better buy: 3 chocolate bars for $1.80
---
12. Coffee cups
- 24 cups for $36 → $36 ÷ 24 = $1.50 each
- 30 cups for $48 → $48 ÷ 30 = $1.60 each
✔ Better buy: 24 coffee cups for $36
