Question

Sue and Bill share a 16-ounce box of cereal. By the end of the week, Sue has eaten 5 8 of the box, and Bill has eaten 1 4 of the box of cereal. How many ounces are left in the box?

Answer 1

Answer: 2 ounce

Explanation:

Given

16 ounce of the box is shared by Sue and Bill

Sue has eaten
`(5)/(8)` of the box

Bill has eaten
`(1)/(4)` of the box

total cereal eaten by them is

`\Rightarrow (5)/(8)+(1)/(4)=(5)/(8)+(2)/(8)\\\\\Rightarrow (7)/(8)`

So, they have eaten this much of the box. Amount left in the box is

`\Rightarrow 1-(7)/(8)\\\\\Rightarrow (1)/(8)`

In ounce it is

`\Rightarrow 16* (1)/(8)\\\\\Rightarrow 2\ \text{ounce}`
