Let’s solve each problem step by step.
---
Problem 1:
Martha bought 18 small cakes. She has 3 children. She wants to divide the cakes equally among them.
We need to find how many cakes each child gets → that means
divide 18 by 3.
18 ÷ 3 = 6
✔ Each child gets 6 cakes.

Problem 2:
Julian’s comic book has 143 frames total. He puts exactly 11 frames on each page.
We need to find how many pages he will have → that means
divide 143 by 11.
Let’s check:
11 × 10 = 110
11 × 13 = 143 (because 11×10=110, 11×3=33; 110+33=143)
So, 143 ÷ 11 = 13
✔ He will have 13 pages.

Problem 3:
Jesse’s wall is 13 feet long. Each poster is 2 feet wide.
First question: How many posters can he fit?
→ Divide 13 by 2.
13 ÷ 2 = 6 with a remainder of 1.
That means he can fit
6 full posters, and there will be
1 foot left over.
Check:
6 posters × 2 feet = 12 feet used
13 - 12 = 1 foot left
✔ 6 posters, 1 foot of white space left.

Final Answer:
1. Each child gets
6 cakes.
2. Julian will have
13 pages.
3. Jesse can fit
6 posters, and
1 foot of white space is left over.
