What is 81.5% of 800?

We need to find 81.5% of 800.

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

So 81.5% means 81.5 out of every 100.

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

Divide the percentage by 100:

81.5 ÷ 100 = 0.815

This means 81.5% = 0.815

Now multiply the decimal by the number:

0.815 × 800 = 652

So 81.5% of 800 = 652

You can also think of it as a fraction:

81.5% of 800 = (81.5/100) × 800

= (81.5 × 800) / 100

= 65200 / 100

= 652
