What is 16000 of 40000 as a percentage?

Answer 1

First, lets do some cancelling to get rid of 3 of the zeros and reduce the ratio. That leaves 16 out of 40. Then we can divide 8 into both to get 2 out of 5. Percentage means "per hundred," and 5 goes into 100 a total of 20 times. That is one fifth, so we have to double that to get 2 fifths, giving us the answer of 40 percent.

Or if you want to use a calculator, divide it out and then multiply the answer by 100 (move the decimal 2 places to the right so 0.4 becomes 40).
