Answer 1

`(7)/(12)` of the cake

Explanation:

add
`(1)/(8)` and
`(1)/(6)` to see the total amount of cake eaten.

a. find the common denominator: 8 x 3 = 24 and 6 x 4 = 24

b. multiply accordingly to get the correct numerator:
`(3)/(24)` +
`(4)/(24)`

c. add:
`(3)/(24)` +
`(4)/(24)` =
`(7)/(24)`

subtract found value from total to find left over cake.

a. 24 - 7 = 14

simplify.

a.
`(14)/(24)` =
`(7)/(12)`

You are left with
`(7)/(12)` of the cake.
