What is 22.5% of 400?

We need to find 22.5% of 400.

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

So 22.5% means 22.5 out of every 100.

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

Divide the percentage by 100:

22.5 ÷ 100 = 0.225

This means 22.5% = 0.225

Now multiply the decimal by the number:

0.225 × 400 = 90

So 22.5% of 400 = 90

You can also think of it as a fraction:

22.5% of 400 = (22.5/100) × 400

= (22.5 × 400) / 100

= 9000 / 100

= 90
