Solution: Intermediate Exercises 1 to 3
1 Library books
Exercise 1
A librarian has 84 books to arrange on 7 shelves. If she wants to put the same number of books on each shelf, how many books will be on each shelf?
Definition:

Equal distribution: Distributing a total quantity evenly among a certain number of recipients.

Division method:
  1. Identify the total quantity (dividend)
  2. Identify the number of groups (divisor)
  3. Divide the total by the number of groups
  4. Verify by multiplying the quotient by the divisor
Total Books
84
Number of Shelves
7
Books per Shelf
12
Step 1: Identify what we know

Total books = 84, Number of shelves = 7

Step 2: Set up the division

We need to divide 84 books among 7 shelves: 84 ÷ 7

Step 3: Calculate the division

84 ÷ 7 = 12 (because 7 × 12 = 84)

Step 4: Check our answer

12 books × 7 shelves = 84 books ✓

Each shelf has 12 books
Final answer:

Each shelf will have 12 books.

Applied rules:

• Equal distribution: Division ensures fairness

• Verification: Multiply quotient by divisor to check

• Division: Total ÷ Number of groups = Amount per group

2 School trip
Exercise 2
72 students are going on a field trip. If 9 students can fit in each van, how many vans are needed for all the students?
Definition:

Grouping: Determining how many groups of a specific size can be formed from a total amount.

Total Students
72
Students per Van
9
Number of Vans
8
Step 1: Identify what we know

Total students = 72, Students per van = 9

Step 2: Set up the division

We need to find how many vans: 72 ÷ 9

Step 3: Calculate the division

72 ÷ 9 = 8 (because 9 × 8 = 72)

Step 4: Check our answer

8 vans × 9 students = 72 students ✓

8 vans are needed
Final answer:

8 vans are needed for all the students.

Applied rules:

• Grouping: Total ÷ Size of each group = Number of groups

• Verification: Number of groups × Size of each group = Total

• Real-world context: Need whole vans, no partial vans

3 Fruit sharing
Exercise 3
A farmer harvested 96 apples and wants to pack them into baskets. If each basket can hold 8 apples, how many baskets will he need? If he gives 3 baskets to his neighbor, how many apples will his neighbor receive?
Definition:

Multi-step problem: A problem requiring multiple operations to reach the final answer.

Total Apples
96
Apples per Basket
8
Total Baskets
12
Step 1: Find total number of baskets needed

96 apples ÷ 8 apples per basket = 12 baskets

Step 2: Find apples given to neighbor

3 baskets × 8 apples per basket = 24 apples

Step 3: Check first calculation

12 baskets × 8 apples = 96 apples ✓

Step 4: Check second calculation

3 baskets × 8 apples = 24 apples

12 baskets needed; 24 apples given to neighbor
Final answer:

The farmer needs 12 baskets, and his neighbor will receive 24 apples.

Applied rules:

• Multi-step problem: Solve one part at a time

• First calculation: Grouping: 96 ÷ 8 = 12

• Second calculation: Multiplication: 3 × 8 = 24

Questions & Answers

Question: Sometimes I see problems with more than one question. How do I handle multi-step division problems?

Answer: Multi-step problems can seem tricky, but follow this approach:

  • Read the entire problem: Don't rush to start calculating
  • Identify each question: Circle or underline what you need to find
  • Solve step by step: Complete one calculation before moving to the next
  • Use previous answers: Sometimes later questions use earlier results
  • Check each step: Make sure each part makes sense

For example, in the apple problem: First find total baskets (96 ÷ 8 = 12), then find apples given to neighbor (3 × 8 = 24). Each step builds on the previous one!

Question: My child sometimes gets the dividend and divisor mixed up. How can I help them remember which is which?

Answer: Here are memory aids to help remember dividend and divisor:

  • Dividend: "The one being DIVIDED" - it's the total amount that gets split up
  • Divisor: "the one that does the DIVIDING" - it's the number of groups or size of groups
  • Position: In "84 ÷ 7 = 12", 84 is the dividend, 7 is the divisor
  • Story method: The dividend is like the "pie" that gets cut, the divisor is the "knife" that cuts it

Practice with simple examples: "20 cookies ÷ 4 people = 5 cookies each" - 20 is the dividend (total cookies), 4 is the divisor (number of people).

Question: How can I be sure my division answer is correct?

Answer: Always check your division by multiplying back:

  • Multiply: Take your answer (quotient) and multiply it by the number you divided by (divisor)
  • Compare: You should get back to your original number (dividend)
  • Example: If 84 ÷ 7 = 12, then check: 12 × 7 = 84 ✓
  • For grouping: If 72 students need 9 per van = 8 vans, check: 8 × 9 = 72 ✓

This works because division and multiplication are opposite operations. If you did the division correctly, multiplying back will give you the starting number!
