30 // 3 = ? 12 6 = ? 17 2 = ? 25 // 5 4 = ? 14 // 7 8 = ? 16 // ? * 5 = 20 Use the examples below to do the following assignments.

Here are the solutions to your math problems:

19. Step 1: Divide 30 by 3. $30 \div 3 = \mathbf{10}$

20. Step 1: Perform the division first. $25 \div 5 = 5$ Step 2: Multiply the result by 4. $5 \times 4 = \mathbf{20}$

21. Step 1: Multiply 12 by 6. $12 \times 6 = \mathbf{72}$

22. Step 1: Perform the division first. $14 \div 7 = 2$ Step 2: Multiply the result by 8. $2 \times 8 = \mathbf{16}$

23. Step 1: Multiply 17 by 2. $17 \times 2 = \mathbf{34}$

24. Step 1: Let the missing number be $x$. The equation is: $16 \div x \times 5 = 20$ Step 2: Divide both sides by 5. $16 \div x = 20 \div 5$ $16 \div x = 4$ Step 3: Solve for $x$. $x = 16 \div 4$ $x = \mathbf{4}$
