What is 31.5% of 400?

We need to find 31.5% of 400.

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

So 31.5% means 31.5 out of every 100.

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

Divide the percentage by 100:

31.5 ÷ 100 = 0.315

This means 31.5% = 0.315

Now multiply the decimal by the number:

0.315 × 400 = 126

So 31.5% of 400 = 126

You can also think of it as a fraction:

31.5% of 400 = (31.5/100) × 400

= (31.5 × 400) / 100

= 12600 / 100

= 126
