x = tablespoons of milk
Proportion:
21 cups of flour / 10 tablespoons of milk = 168 cups of flour / x tablespoons of milk
21 / 10 = 168 / x
Cross multiply
21 ∙ x = 10 ∙ 168
21 x = 1680
Divide both sides by 21
x = 1680 / 21 = 21 ∙ 80 / 21 = 80
80 tablespoons of milk
Proportion:
21 cups of flour / 10 tablespoons of milk = 168 cups of flour / x tablespoons of milk
21 / 10 = 168 / x
Cross multiply
21 ∙ x = 10 ∙ 168
21 x = 1680
Divide both sides by 21
x = 1680 / 21 = 21 ∙ 80 / 21 = 80
80 tablespoons of milk
