What is 3.5% of 6400?

We need to find 3.5% of 6400.

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

So 3.5% means 3.5 out of every 100.

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

Divide the percentage by 100:

3.5 ÷ 100 = 0.035

This means 3.5% = 0.035

Now multiply the decimal by the number:

0.035 × 6400 = 224

So 3.5% of 6400 = 224

You can also think of it as a fraction:

3.5% of 6400 = (3.5/100) × 6400

= (3.5 × 6400) / 100
