What is 2.25% of 800?

We need to find 2.25% of 800.

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

So 2.25% means 2.25 out of every 100.

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

Divide the percentage by 100:

2.25 ÷ 100 = 0.0225

This means 2.25% = 0.0225

Now multiply the decimal by the number:

0.0225 × 800 = 18

So 2.25% of 800 = 18

You can also think of it as a fraction:

2.25% of 800 = (2.25/100) × 800

= (2.25 × 800) / 100

= 1800 / 100

= 18
