The recipe is for 4 pancakes.
She needs to make 60 pancakes.
60/4 = 15
She needs to make 15 times the recipe.
The recipe calls for 1/3 cup of mix, so she needs 15 times that amount.

15 * 1/3 = 15/1 * 1/3 = 15/3 = 5

She needs 5 cups of mix.

5 cups
1/3 divided into 4 = 1/3x 1/4= 1/2
1/12 per unit
1/12 x60 = 60/12 = 5
