Grade 6 math worksheet focused on finding percentages of numbers, designed for practice without a calculator.

Let's solve each problem step by step. The goal is to find the percentage of a number.

We use the formula:
$$
\text{Percentage of a number} = \frac{\text{Percentage}}{100} \times \text{Number}
$$

First Column (Without Calculator)

1. 15% of 80
$$
\frac{15}{100} \times 80 = 0.15 \times 80 = 12
$$

2. 25% of 40
$$
\frac{25}{100} \times 40 = 0.25 \times 40 = 10
$$

3. 30% of 90
$$
\frac{30}{100} \times 90 = 0.30 \times 90 = 27
$$

4. 40% of 75
$$
\frac{40}{100} \times 75 = 0.40 \times 75 = 30
$$

5. 20% of 150
$$
\frac{20}{100} \times 150 = 0.20 \times 150 = 30
$$

6. 35% of 10
$$
\frac{35}{100} \times 10 = 0.35 \times 10 = 3.5
$$

7. 60% of 60
$$
\frac{60}{100} \times 60 = 0.60 \times 60 = 36
$$

8. 25% of 60
$$
\frac{25}{100} \times 60 = 0.25 \times 60 = 15
$$

9. 10% of 33
$$
\frac{10}{100} \times 33 = 0.10 \times 33 = 3.3
$$

10. 90% of 200
$$
\frac{90}{100} \times 200 = 0.90 \times 200 = 180
$$

Second Column (Can Use Calculator if Needed)

11. 85% of 108
$$
\frac{85}{100} \times 108 = 0.85 \times 108 = 91.8
$$

12. 40% of 88
$$
\frac{40}{100} \times 88 = 0.40 \times 88 = 35.2
$$

13. 15% of 68
$$
\frac{15}{100} \times 68 = 0.15 \times 68 = 10.2
$$

14. 55% of 28
$$
\frac{55}{100} \times 28 = 0.55 \times 28 = 15.4
$$

15. 30% of 480
$$
\frac{30}{100} \times 480 = 0.30 \times 480 = 144
$$

16. 27% of 235
$$
\frac{27}{100} \times 235 = 0.27 \times 235 = 63.45
$$

17. 44% of 97
$$
\frac{44}{100} \times 97 = 0.44 \times 97 = 42.68
$$

18. 62% of 82
$$
\frac{62}{100} \times 82 = 0.62 \times 82 = 50.84
$$

19. 47% of 67
$$
\frac{47}{100} \times 67 = 0.47 \times 67 = 31.49
$$

20. 82% of 124
$$
\frac{82}{100} \times 124 = 0.82 \times 124 = 101.68

💡 Tips for Solving Without a Calculator:

- 10% of a number: Move decimal one place left.
- 5%: Half of 10%
- 25%: Divide by 4
- 50%: Divide by 2
- 1%: Move decimal two places left
- Use these to build other percentages (e.g., 15% = 10% + 5%)
