What is 0.3% of 12800?

We need to find 0.3% of 12800.

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

So 0.3% means 0.3 out of every 100.

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

Divide the percentage by 100:

0.3 ÷ 100 = 0.003

This means 0.3% = 0.003

Now multiply the decimal by the number:

0.003 × 12800 = 38.4

So 0.3% of 12800 = 38.4

You can also think of it as a fraction:

0.3% of 12800 = (0.3/100) × 12800

= (0.3 × 12800) / 100

= 3840 / 100

= 38.4
