Question

Cara and Glen share a 24-ounce box of cereal. By the end of the week, Cara has eaten 3/8 of the box, and Glen has eaten 1/4 of the box of cereal. How many ounces are left in the box?

Answer 1

9 ounces

Explanation:

Let x be the ounces left in the box.

Given:

Total ounces in box = 24

Cara has eaten 3/8 of the box,

So, Cara eaten =
`(3)/(8)* 24`

Cara eaten =
`(3* 24)/(8)`

Cara eaten =
`3* 3`

Cara eaten =
`9`

So, Cara has eaten 9 ounce of the box of cereal.

Glen has eaten 1/4 of the box of cereal.

So, Glan eaten =
`(1)/(4)* 24`

Glan eaten =
`(1* 24)/(4)`

Glan eaten =
`1* 6`

Glan eaten =
`6`

So, Glan has eaten 6 ounce of the box of cereal.

Therefore, the sum of the Cara and Glan ounces =
`6+9=15`.

So total left ounces in box = 24-15 = 9

Therefore, The ounces left in the box is 9.
