Answer: 15 cakes

Step-by-step explanation:

For 1 cake, Carol uses 1/3 cup of milk.

When she has 5 cups of milk left, the number of cake is not known yet.

Let the number of Unknown cakes be y.

1/3 = 1 ... equation i

5 = y ... equation ii

Divide equation I by ii

1/3 / 5 = 1/y

1/15 = 1/y

Cross multiply

Y = 15

She can make 15 cakes from 5 cups of milk
