If the part is 18 and the whole is 25 whats the percent?

First you would have to convert the number to a decimal. To convert a fraction to a decimal, divide the denominator by the numerator. So 18/25=0.72

Next to convert a decimal to a percent, move the decimal point over two places then add a percent sign.

so .72 becomes 72%

18/25 as a percent is 72%

There is 240 red cars and there is 400 blue cars because 240/3=80 and 80*5=400
