Question:
If one gallon requires a certain amount of coloring, $6813_w19_h37.png$ gallons of custom color paint will require $6813_w19_h37.png$ times as much coloring. So, this is a multiplication problem: multiply the amount of coloring needed for 1 gallon by $6813_w19_h37.png$. $5713_w53_h37.png$ Convert $5510_w19_h37.png$ to an improper fraction ($1763_w9_h37.png$) $1403_w44_h37.png$ $4557_w18_h38.png$ You could also use a proportion to solve this problem, but it is not as simple as the above method.
