What is 1.09% of 6400?

We need to find 1.09% of 6400.

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

So 1.09% means 1.09 out of every 100.

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

Divide the percentage by 100:

1.09 ÷ 100 = 0.0109

This means 1.09% = 0.0109

Now multiply the decimal by the number:

0.0109 × 6400 = 69.76

So 1.09% of 6400 = 69.76

You can also think of it as a fraction:

1.09% of 6400 = (1.09/100) × 6400

= (1.09 × 6400) / 100

= 6976 / 100
