how do u change a ratio into a percent

Divide the numerator by the denominator. Multiply the answer by 100 to find the percent. You can do this by moving the decimal point two places to the right.
Example: 3/4 = 0.75 = 75% 
Examples: 2/ 5 = ?/100
we multiplied the 5 with 20 to be 100 then we have to multiply the 2 with 20 as well
then 2/5 = 40/ 100
40%
