Question

Andre made a cleaning solution using 7/8 cup of water and 1/4 cup of vinegar.He used 1/3 cup of the solution to wash the windows in his home. Write an expression showing how to find the amount of cleaning solution, in cups,that Andre has left.

Answer 1

well first you have to make 1/4 into a fraction with 8 as a denominator so that would be ,2/8. then add 2/8 and 7/8 together and get 9/8 which=1 1/8.then change 1 1/8 and 1/3 so they have the same denominater, them just subtract

Answer 2

He would have 19/24 cup of solution left.

7/8+1/4
7/3+2/8
9/8-1/3
27/24-8/24=19/24
