What is 42.5% of 400?

We need to find 42.5% of 400.

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

So 42.5% means 42.5 out of every 100.

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

Divide the percentage by 100:

42.5 ÷ 100 = 0.425

This means 42.5% = 0.425

Now multiply the decimal by the number:

0.425 × 400 = 170

So 42.5% of 400 = 170

You can also think of it as a fraction:

42.5% of 400 = (42.5/100) × 400

= (42.5 × 400) / 100

= 17000 / 100

= 170
