What is 16.5% of 400?

We need to find 16.5% of 400.

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

So 16.5% means 16.5 out of every 100.

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

Divide the percentage by 100:

16.5 ÷ 100 = 0.165

This means 16.5% = 0.165

Now multiply the decimal by the number:

0.165 × 400 = 66

So 16.5% of 400 = 66

You can also think of it as a fraction:

16.5% of 400 = (16.5/100) × 400

= (16.5 × 400) / 100

= 6600 / 100

= 66
