Calculate the number of batches of paint one pint of red could make.
What about the yellow paint?
Now, calculate the number of batches one gallon of green paint will make.
It would be the same number of batches since you have twice as much yellow paint but the amount needed is twice as much as the red.
There are 4 quarts to a gallon. Each quart has 2 pints. So you can make 8 batches of the special green with one gallon of the standard green.Now set up a proportion and solve.
