Keith wants to make cupcakes. To make cupcakes he needs 1 3/10 cups of flour per batch of cupcakes. If Keith has 13 cups of flour, then how many batches of cupcakes can Keith make?

Answer: Keith can make 10 batches of cupcakes.

Step-by-step explanation:

To make cupcakes, he needs 1 3/10 cups of flour per batch of cupcakes. Converting 1 3/10 cups of flour into improper fraction, it becomes 13/10 cups of flour.

Let x represent the number of batches of cupcakes that Keith can make If Keith has 13 cups of flour,. Therefore,

13/10 cups of flour = 1 batch of cupcakes

13 cups of flour = x batch of cupcakes

Cross multiplying, it becomes

13/10 * x = 13 * 1

13x/10 = 13

13x = 13 * 10 = 130

x = 130/13 = 10
