Drake knows that the ratio of eggs to cups of milk in his favorite pancake recipe is 3:5. He finds four pancake recipes for larger batches. Each recipe has a different ratio of eggs to cups of milk. Which ratio of eggs to cups of milk is proportional to the ratio in Drake’s favorite recipe?
Ratios are proportional when the numbers in the ratio are multiply or divide by the same number. Ex. 3:5 = 6:10 = 12:20 = 9:15 (cross multiply the fractions and the results are the same 3/5 = 6/10)
