If the paint is 30% yellow, and you used 72 ounces of yellow, all you have to do is divide 72 by 30% to get the whole amount of ounces of paint made.
72 ÷ 0.30 = 240
In the last batch, you made 240 ounces of melon madness paint.
5/8 = 2/3 the entire box
Half of 2/3 is 1/3, and 2/3 + 1/3 = 1
So find half of 5/8 and add it to 5/8.
5/8 * 1/2 = 5/16
5/8 + 5/16
Change 5/8 to a fraction with a denominator of 16:
10/16 + 5/16 = 15/16
So the original weight is 15/16 pounds.
= -3/2 x -21/4
= 63/8
=7.875
The answer to the problem is 13ab
