Explanation:

7. Step1: Convert % to decimal

$8\% = 0.08$

7. Step2: Multiply by 50

$0.08 \times 50 = 4$

8. Step1: Set up percent equation

$\text{Percent} = \frac{52}{260} \times 100\%$

8. Step2: Calculate the value

$0.2 \times 100\% = 20\%$

9. Step1: Convert % to decimal

$75\% = 0.75$

9. Step2: Divide to find the number

$\frac{30}{0.75} = 40$

10. Step1: Convert % to decimal

$15\% = 0.15$

10. Step2: Multiply by 24

$0.15 \times 24 = 3.6$

11. Step1: Convert % to decimal

$90\% = 0.9$

11. Step2: Multiply by total questions

$0.9 \times 50 = 45$

12. Step1: Set up percent equation

$\text{Percent} = \frac{4}{40} \times 100\%$

12. Step2: Calculate the value

$0.1 \times 100\% = 10\%$

Answer:

1. $4$
2. $20\%$
3. $40$
4. $3.6$
5. $45$
6. $10\%$
