Problem: Solve the division problems using repeated subtraction.
The worksheet provides an example for solving division problems using repeated subtraction. Let's break down the process and solve each problem step by step.
####
Example:
12 ÷ 4 = 3
- Start with 12.
- Subtract 4 repeatedly until you reach 0:
- 12 - 4 = 8
- 8 - 4 = 4
- 4 - 4 = 0
- You subtracted 4 a total of 3 times, so 12 ÷ 4 = 3.
Now, let's solve the rest of the problems using the same method.
---
Problem 1: 18 ÷ 2 = ?
- Start with 18.
- Subtract 2 repeatedly until you reach 0:
- 18 - 2 = 16
- 16 - 2 = 14
- 14 - 2 = 12
- 12 - 2 = 10
- 10 - 2 = 8
- 8 - 2 = 6
- 6 - 2 = 4
- 4 - 2 = 2
- 2 - 2 = 0
- You subtracted 2 a total of 9 times, so 18 ÷ 2 = 9.
---
Problem 2: 6 ÷ 3 = ?
- Start with 6.
- Subtract 3 repeatedly until you reach 0:
- 6 - 3 = 3
- 3 - 3 = 0
- You subtracted 3 a total of 2 times, so 6 ÷ 3 = 2.
---
Problem 3: 21 ÷ 3 = ?
- Start with 21.
- Subtract 3 repeatedly until you reach 0:
- 21 - 3 = 18
- 18 - 3 = 15
- 15 - 3 = 12
- 12 - 3 = 9
- 9 - 3 = 6
- 6 - 3 = 3
- 3 - 3 = 0
- You subtracted 3 a total of 7 times, so 21 ÷ 3 = 7.
---
Problem 4: 15 ÷ 5 = ?
- Start with 15.
- Subtract 5 repeatedly until you reach 0:
- 15 - 5 = 10
- 10 - 5 = 5
- 5 - 5 = 0
- You subtracted 5 a total of 3 times, so 15 ÷ 5 = 3.
---
Problem 5: 40 ÷ 10 = ?
- Start with 40.
- Subtract 10 repeatedly until you reach 0:
- 40 - 10 = 30
- 30 - 10 = 20
- 20 - 10 = 10
- 10 - 10 = 0
- You subtracted 10 a total of 4 times, so 40 ÷ 10 = 4.
---
Problem 6: 9 ÷ 3 = ?
- Start with 9.
- Subtract 3 repeatedly until you reach 0:
- 9 - 3 = 6
- 6 - 3 = 3
- 3 - 3 = 0
- You subtracted 3 a total of 3 times, so 9 ÷ 3 = 3.
---
Problem 7: 16 ÷ 4 = ?
- Start with 16.
- Subtract 4 repeatedly until you reach 0:
- 16 - 4 = 12
- 12 - 4 = 8
- 8 - 4 = 4
- 4 - 4 = 0
- You subtracted 4 a total of 4 times, so 16 ÷ 4 = 4.
---
Problem 8: 35 ÷ 7 = ?
- Start with 35.
- Subtract 7 repeatedly until you reach 0:
- 35 - 7 = 28
- 28 - 7 = 21
- 21 - 7 = 14
- 14 - 7 = 7
- 7 - 7 = 0
- You subtracted 7 a total of 5 times, so 35 ÷ 7 = 5.
---
Problem 9: 24 ÷ 3 = ?
- Start with 24.
- Subtract 3 repeatedly until you reach 0:
- 24 - 3 = 21
- 21 - 3 = 18
- 18 - 3 = 15
- 15 - 3 = 12
- 12 - 3 = 9
- 9 - 3 = 6
- 6 - 3 = 3
- 3 - 3 = 0
- You subtracted 3 a total of 8 times, so 24 ÷ 3 = 8.

Final Answers:
\[
\boxed{
\begin{array}{ll}
18 \div 2 = 9 & 6 \div 3 = 2 \\
21 \div 3 = 7 & 15 \div 5 = 3 \\
40 \div 10 = 4 & 9 \div 3 = 3 \\
16 \div 4 = 4 & 35 \div 7 = 5 \\
24 \div 3 = 8 &
\end{array}
}
\]
