Use the examples below to do the following assignments. Examples: (i) 4 3 = 12 (ii) 6 / 2 = 3 (iii) 2 2 = 4 (iv) 4 / 2 = 2

Here are the solutions to the multiplication and division problems:

1. Step 1: Multiply 8 by 3. $8 \times 3 = \mathbf{24}$

2. Step 1: Multiply 6 by 6. $6 \times 6 = \mathbf{36}$

3. Step 1: Divide 12 by 1. $12 \div 1 = \mathbf{12}$

4. Step 1: Multiply 3 by 3. $3 \times 3 = \mathbf{9}$

5. Step 1: Multiply 16 by 2. $16 \times 2 = \mathbf{32}$

6. Step 1: Multiply 7 by 6. $7 \times 6 = \mathbf{42}$

7. Step 1: Divide 20 by 10. $20 \div 10 = \mathbf{2}$

8. Step 1: Divide 21 by 7. $21 \div 7 = \mathbf{3}$

9. Step 1: Divide 40 by 8. $40 \div 8 = \mathbf{5}$

10. Step 1: Divide 26 by 13. $26 \div 13 = \mathbf{2}$

11. Step 1: Multiply 16 by 4. $16 \times 4 = \mathbf{64}$

12. Step 1: Divide 24 by 3. $24 \div 3 = \mathbf{8}$

13. Step 1: Multiply 9 by 8. $9 \times 8 = \mathbf{72}$

14. Step 1: Multiply 6 by 8. $6 \times 8 = 48$ Step 2: Divide the result by 2. $48 \div 2 = \mathbf{24}$

15. Step 1: To find the missing number, multiply 9 by 4. $\boxed{36} \div 4 = 9$

16. Step 1: Divide 49 by 7. $49 \div 7 = 7$ Step 2: To make the equation true ($7 \times missing = 7$), the missing number must be 1. $49 \div 7 \times \mathbf{1} = 7$

17. Step 1: Multiply 12 by 3. $12 \times 3 = 36$ Step 2: Multiply the result by 2. $36 \times 2 = \mathbf{72}$

18. Step 1: Multiply 7 by 8. $7 \times 8 = \mathbf{56}$
