Question

My cupcake recipe makes 12 cupcakes and requires 3/2 sticks of butter. I can only buy whole sticks of butter. How many whole sticks of butter must I buy to make 100 cupcakes?

Answer 1

We find out the ratio 100: 12= 25/3
We need the number of sticks of butter: 25/3 x 3/2= 25/2=12.5
That means you must buy 13 sticks of butter
