Math worksheet for calculating percentages using real-world examples.

To find the percent, we use this simple rule:
Percent = (Part ÷ Whole) × 100

Here is the step-by-step calculation for each problem on the list:

1. What percent is 3 chairs out of 12 chairs?

* Multiply by 100: $0.25 \times 100 = 25\%$

2. What percent is 5 pigs out of 20 pigs?
* Divide 5 by 20: $5 \div 20 = 0.25$
* Multiply by 100: $0.25 \times 100 = 25\%$

3. What percent is 28 stones out of 35 stones?
* Divide 28 by 35: $28 \div 35 = 0.8$

5. What percent is 24 plates out of 200 plates?
* Divide 24 by 200: $24 \div 200 = 0.12$
* Multiply by 100: $0.12 \times 100 = 12\%$

6. What percent is 80 pens out of 160 pens?
* Divide 80 by 160: $80 \div 160 = 0.5$
* Multiply by 100: $0.5 \times 100 = 50\%$

7. What percent is 8 mice out of 20 mice?
* Divide 8 by 20: $8 \div 20 = 0.4$
