Are you referring to this question?
Ann and Margie had a total of 3 gallons of paint to share for a project. They had 1 gallon each of red paint, blue paint, and yellow paint.
• To complete the project, Ann used 3/8 of the red paint, 1/4 of the blue paint, and 1/2 of the yellow paint.
• To complete the project, Margie used 1/2 of the red paint, 5/8 of the blue paint, and 1/8 of the yellow paint.
How many total gallons of each color of paint were left after both girls had finished the project?
If so, the answer is:
Given: Blue paint used: 1/4 and 5/8
Red Paint: 3/8 and 1/2
Yellow paint: 1/2 and 1/8
Solve:
Add all used paint per color.
Blue paint used: 1/4 and 5/8, makes up 7/8
Red Paint used: 3/8 and 1/2, makes up 7/8
Yellow paint used: 1/2 and 1/8, makes up 5/8
Subtract each total paint used from 8/8 (8/8 is = to 1, which denotes 1 gallon/paint)
The remaining paint would be:
Blue paint = 1/8
Red Paint=1/8
Yellow paint= 3/8
