If you know the part and the whole, you're able to find the percentage. In order to do it, you set up a proportion. The proportion is: Part/Whole=Percentage/100. Therefore, you fill in what you know. For example, if you want to find out what percent 48 is of 70, do: 48/70 = X/100. Then cross-multiply: (48 x 100)/70 = percentage.
