What is 0.2% of 6400?

We need to find 0.2% of 6400.

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

So 0.2% means 0.2 out of every 100.

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

Divide the percentage by 100:

0.2 ÷ 100 = 0.002

This means 0.2% = 0.002

Now multiply the decimal by the number:

0.002 × 6400 = 12.8

So 0.2% of 6400 = 12.8

You can also think of it as a fraction:

0.2% of 6400 = (0.2/100) × 6400

= (0.2 × 6400) / 100

= 1280 / 100

= 12.8
