Question

Robin had 7/8 pound of butter when she started baking a cake. She used 1/4 pound of butter while baking. How much butter was left after she was done baking?

Answer 1

`(5)/(8)` butter was left after she was done baking.

Explanation:

Robin had 7/8 pound of butter when she started baking a cake. She used 1/4 pound of butter while baking.

We need to find how much butter was left after she was done baking.

It can be calculated as follows,

Left =

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

Hence,
`(5)/(8)` butter was left after she was done baking
