2 to 5 equals what percent?

Answer 1

40%

Theory:

2/5 equals 4/10.

10x10=100, so 4x10=40, so 40%.

A percentage simply means out of 100, so it would mean 40 out of 100.

Percent means "for every 100" or, in other words, "out of 100", so when converting a fraction to a percentage, you are making it an equivalent fraction out of 100. The easiest way to do this is to multiply by 100:

2/5 = 2/5 x 100 % = 40 %

As equivalent fractions, this becomes:

since 100 ÷ 5 = 20, multiply the numerator and denominator by 20:

2/5 = 2x20/5x20 = 40/100 = 40 %
