Answer 1

Maybe this might help a bit what you have to do is subtract each fraction. if you subtract 1/3 and 3/4 and change the dinominators to mach then you answer will be 1/4 for a gallon of yellow paint and for blue paint you subtract and you do the same thing and for 7/8-3/4 your answer will be 1/8 after you have made equal denominator. 3/4 is the amount of paint being removed so that's what you will subtract
