To find the percent of anything, you change the percent to a decimal, and multiply. Finding the percent of a sum is no different. ex: 10% of (30 + 100) I can use the distributive property to take 10% of 30, then add 10% of 100. .10(30 + 100) = .10*30 + .10*100 = 3 + 10 = 13 In order to see how this works, let's not distribute. .10(30+100) and instead, add 30 +100 first, then take the percent. .10(130) = 13 We get the same answer! You can take the percent of the whole thing, or you can take the percent of the pieces that add up to the whole.
