The ratio of blue paint to yellow paint can be determined by determining the simplest form of the paints used: 4 : 6 = 2: 3
Total blue paint cans used on the first and second day = 4 + 6 = 10
Blue paint cans remaining = 14 - 10 = 4
Total yellow paint cans used on the first and second day = 6 + 9 = 15 cans
Yellow paint cans remaining = 20 - 15 = 5 cans
