Let’s solve each problem one by one, step by step.
---
Problem 1:
> Both Matt and Bob had 8 limes. Maria had 4 limes. How many limes were there in all?
- Matt has 8 limes.
- Bob also has 8 limes (because it says “both Matt and Bob had 8” — that means each of them has 8).
- Maria has 4 limes.
- So total = 8 + 8 + 4 =
20
Check the options:
- 8+4=12 → too small, forgot Bob
- 8+4=13 → wrong math
- 8+8+4=20 → correct!
✔ Correct answer for #1:
8+8+4=20

Problem 2:
> Sara and Jane each had 6 apples. The girls gave 1 apple away. How many apples do Sara and Jane have in all now?
- Sara has 6 apples.
- Jane has 6 apples.
- Together they start with 6 + 6 = 12 apples.
- They gave away 1 apple → so subtract 1: 12 - 1 =
11
Check the options:
- 6+1+1=8 → doesn’t make sense
- 6+6-1=11 → yes! That matches our thinking
- 6+6+1+1=14 → added instead of subtracted
✔ Correct answer for #2:
6+6-1=11

Problem 3:
> Together Mary and Joe had 12 eggs. If Mary had 9 eggs, how many eggs did Joe have?
- Total eggs = 12
- Mary has 9
- So Joe must have the rest: 12 - 9 =
3
Check the options:
- 12+9=21 → adding, but we need to find what’s left
- 12-9=17 → wrong subtraction
- 12-9=3 → correct!
✔ Correct answer for #3:
12-9=3
---
Final Answer:
1. 8+8+4=20
2. 6+6-1=11
3. 12-9=3
