What is 7.5% of 400?

We need to find 7.5% of 400.

The word "percent" means "per hundred" or "out of 100".

So 7.5% means 7.5 out of every 100.

To calculate with percentages, we first convert to a decimal.

Divide the percentage by 100:

7.5 ÷ 100 = 0.075

This means 7.5% = 0.075

Now multiply the decimal by the number:

0.075 × 400 = 30

So 7.5% of 400 = 30

You can also think of it as a fraction:

7.5% of 400 = (7.5/100) × 400

= (7.5 × 400) / 100

= 3000 / 100

= 30
