Patty has an icing recipe that makes 24 cupcakes and the ratio of cups of sugar to sticks of butter is 3:1. If she has to make 60 cupcakes, how much of each ingredient will she need?

 $\dfrac {60}{24}=\dfrac 5 2 \\ \dfrac 5 2 \times 3 = \dfrac {15}{2} \mbox{ cups of sugar.} \\ \dfrac 5 2 \times 1 = \dfrac 5 2 \mbox{ sticks of butter.}$
