What is 2.5% of 1600?

We need to find 2.5% of 1600.

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

So 2.5% means 2.5 out of every 100.

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

Divide the percentage by 100:

2.5 ÷ 100 = 0.025

This means 2.5% = 0.025

Now multiply the decimal by the number:

0.025 × 1600 = 40

So 2.5% of 1600 = 40

You can also think of it as a fraction:

2.5% of 1600 = (2.5/100) × 1600

= (2.5 × 1600) / 100

= 4000 / 100

= 40
