Question

A recipe called for using 5 1/8 cups of flour before baking and another 8 7/9 cups after baking. What is the total amount of flour needed in the recipe?​

Answer 1

Answer: 13
`(65)/(72)`

Explanation:

This question is asking us to find the total flour used, so we will add the two amounts together.

5 1/8 + 8 7/9

-

5 + 8 = 13

1/8 + 7/9 = 9/72 + 56/72 = 65/72

-

13 + 65/72 = 13
`(65)/(72)`

The recipe calls for 13
`(65)/(72)` cups of flour.
