Calculating Percentages

To solve the given percentages, we can use two different methods.

# Method 1: Using Direct Calculation

1. 3% of 400: - To find 3% of 400, we can directly calculate it as 3/100 * 400 = 12. - Therefore, 3% of 400 is 12.

2. 9% of 250: - Similarly, 9% of 250 can be calculated as 9/100 * 250 = 22.5. - Therefore, 9% of 250 is 22.5.

3. 25% of 18: - 25% of 18 can be calculated as 25/100 * 18 = 4.5. - Therefore, 25% of 18 is 4.5.

4. 50% of 70: - Finally, 50% of 70 can be calculated as 50/100 * 70 = 35. - Therefore, 50% of 70 is 35.

# Method 2: Using Multiplication

Alternatively, we can also calculate these percentages by multiplying the given numbers with the percentage in decimal form.

1. 3% of 400: - 3% of 400 can be calculated as 0.03 * 400 = 12. - Therefore, 3% of 400 is 12.

2. 9% of 250: - Similarly, 9% of 250 can be calculated as 0.09 * 250 = 22.5. - Therefore, 9% of 250 is 22.5.

3. 25% of 18: - 25% of 18 can be calculated as 0.25 * 18 = 4.5. - Therefore, 25% of 18 is 4.5.

4. 50% of 70: - Finally, 50% of 70 can be calculated as 0.50 * 70 = 35. - Therefore, 50% of 70 is 35.
