To get a percentage, you will first have to create some form of fraction (or decimal fraction) and then multiply it by 100. Examples: Mark got 17 questions out of 20 correct on a test. What percentage did he anwser correctly? Step One 17 out of 20 is 17/20 Step Two Multiply 17/20 by 100 17/20 x 100/1 = 1700/20 = 85% There are 30 children in a class. 18 are girls and 12 are boys. What percentage of the class are boys? Step One 18 out of 30 is 18/30 Step Two 18/20 x 100/1 = 1800/30 = 60%
