To change a fraction to a percent, treat it like a division problem. For example, to make 1/4 a percent, divide the numerator by the denominator. 1 ÷ 4 = 0.25.
Next, move the decimal point two places to the right. That changed 0.25 to 25, and just add the percent symbol. 25%
AND BAM! You've got yourself a fraction changed to a percent. 1/4 = 25%
