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.
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
