Let’s solve each problem one by one.
---
Problem 1:
You’re texting your boyfriend/girlfriend overseas.
- First text costs $0.35
- Each extra text costs $0.08
- You have $0.75 total
Step 1: Subtract the cost of the first text from your total money.
$0.75 - $0.35 = $0.40 left for additional texts.
Step 2: Divide that by the cost per additional text.
$0.40 ÷ $0.08 = 5 additional texts.
Step 3: Add the first text to get total number of texts.
1 + 5 =
6 texts
✔ Check:
First text: $0.35
Next 5 texts: 5 × $0.08 = $0.40
Total: $0.35 + $0.40 = $0.75 → Correct!

Problem 2:
You bought 5 pounds of hamburger meat.
Each quarter pounder weighs 0.25 pounds.
How many can you make?
Divide total meat by weight per burger:
5 ÷ 0.25 = ?
Think: How many 0.25s are in 5?
Since 0.25 is 1/4, then 5 ÷ (1/4) = 5 × 4 =
20
✔ Check: 20 burgers × 0.25 lbs = 5 lbs → Correct!

Problem 3 (Part A):
Dollhouse has 24 windows.
Each needs 3.75 inches of fabric.
Total fabric needed:
24 × 3.75
Break it down:
24 × 3 = 72
24 × 0.75 = 18 (because 0.75 is 3/4, and 24 × 3/4 = 18)
So 72 + 18 =
90 inches
✔ Check: 24 × 3.75 = 90 → Correct!
---
Problem 3 (Part B):
You have 8 feet of fabric.
There are 12 inches in a foot → so 8 × 12 =
96 inches
You used 90 inches for curtains (from Part A).
Leftover: 96 - 90 =
6 inches
✔ Check: 96 - 90 = 6 → Correct!
---
Problem 4 (Part A):
Recipe needs 2.5 cups sugar.
You have 1.75 cups.
How much more do you need?
2.5 - 1.75 = ?
Write as decimals aligned:
2.50
–1.75
———
0.75
So you need
0.75 more cups
✔ Check: 1.75 + 0.75 = 2.5 → Correct!
---
Problem 4 (Part B):
Neighbor lends you 2 cups.
You already had 1.75 cups.
Now you have: 1.75 + 2 =
3.75 cups
Recipe only needs 2.5 cups.
Extra sugar: 3.75 - 2.5 =
1.25 cups
✔ Check: 3.75 - 2.5 = 1.25 → Correct!
---
Final Answer:
1. 6 texts
2. 20 quarter pounders
3. 90 inches of fabric needed; 6 inches leftover for pillows
4. 0.75 more cups needed; 1.25 cups extra after borrowing
