To FInd:

Amount of sugar needed to make 9 cupcakes

Explanation:

For questions like this, we can use the unitary method.

Unitary Method states that we always find the amount needed for 1 unit. Once we know the amount needed for 1 unit, we multiply the quantity by the number of units we needed.

Example:

1 unit = 3

To Find 5 units, we multiply 3 with 5 units:

5 units = 3 x 5

5 units = 15

Solution:

1 cupcake = 2/12 cup of sugar

9 cupcakes = 2/12 x 9

9 cupcakes = 18/12

9 cupcakes = 3/2

Answer: 9 cupcakes need 3/2 cups of sugar
