a. There are 16 cups in a gallon.... so we have ( 1 + 5/8) * 16 = 26 cups and the red is 2/5 of this = 10.4 cups
And the blue is 1/4 of this = 6.5 cups
b. 3/8 gallon = (3/8) * 16 = 6 cups
Red amount = (2/5)(6) = 12/5 = 2.5 cups
Blue amount = (1/4)(6)= 6/4 = 3/2 = 1.5 cups
White amount = (1/10) * 6 = 6/10 = 3/5 cups
