What is 10.2% of 6400?

We need to find 10.2% of 6400.

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

So 10.2% means 10.2 out of every 100.

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

Divide the percentage by 100:

10.2 ÷ 100 = 0.102

This means 10.2% = 0.102

Now multiply the decimal by the number:

0.102 × 6400 = 652.8

So 10.2% of 6400 = 652.8

You can also think of it as a fraction:

10.2% of 6400 = (10.2/100) × 6400

= (10.2 × 6400) / 100

= 65280 / 100

= 652.8
