Let’s go step by step to solve the problem.

Problem 5a:
> The book of Psalms in the Bible contains 150 chapters. How many chapters are in 6 old books complete?
This is a multiplication problem.
We know:
- 1 book = 150 chapters
- We have 6 books
So, we multiply:
150 × 6
Let’s break it down:
150 × 6 = (100 × 6) + (50 × 6)
= 600 + 300
=
900
✔ So, 6 books × 150 chapters each =
900 chapters

Problem 5b:
> Mrs Wheeler has 17 boys and 15 girls in her Sunday school class. How many children are there?
This is an addition problem.
We add boys and girls together:
17 + 15
Break it down:
17 + 15 = (10 + 10) + (7 + 5)
= 20 + 12
=
32
✔ So, total children =
32

Problem 5c:
> Mrs Wheeler told the class about a trip she once took. She went to the seaside. She travelled 104 miles there and 104 miles back. How many miles did she travel altogether?
This is also addition — or multiplication if you think of it as 2 trips of 104 miles.
Either way:
104 + 104 = 208
Or:
104 × 2 = 208
✔ Total miles traveled =
208
---
All problems solved correctly.
Final Answer:
a. 900
b. 32
c. 208
