Abigail wants to make 60% more pancakes than the recipe calls for, if it calls for 1/2 cup flour, how much would she need?

Answer 1

Percent change is original times 1 +/- the percent change: O(1 +/- %).

A percent is a number divided by 100. 60% = 60/100 = .6.

1/2=.5 = the original amount.

.5 * (1+.6) = ..5 * (1.6) = .8 of a cup = 8/10 = 4/5 of a cup.
