Calculus is a form of math its not a problem so there would be no formula
There is 9 serving of 7 fluid ounces with a remainder of 1 fluid ounce
if you meant 8 fluid ounce servings then it would be 8 servings with no remainder
1/2 + 3/x = 3/4
3/x = 3/4 - 1/2
3/x = 3/4 - 2/4
3/x = 1/4....this is a proportion, so we cross multiply
(1)(x) = (3)(4)
x = 12
check..
1/2 + 3/12 = 3/4
6/12 + 3/12 = 3/4
9/12 = 3/4
3/4 = 3/4 (correct)
so x = 12
