What is 100.5% of 800?

We need to find 100.5% of 800.

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

So 100.5% means 100.5 out of every 100.

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

Divide the percentage by 100:

100.5 ÷ 100 = 1.005

This means 100.5% = 1.005

Now multiply the decimal by the number:

1.005 × 800 = 804

So 100.5% of 800 = 804

You can also think of it as a fraction:

100.5% of 800 = (100.5/100) × 800

= (100.5 × 800) / 100

= 80400 / 100

= 804
