3 1 1/2
4 2

A bakery is making loaves of French bread. The recipe calls for 2 cups of flour per loaf of bread. The data table shows how much flour the bakery needs depending on the number of loaves it intends to make. At which ratio in the data table does the constant of proportionality appear? Write your answer as an ordered pair inside the parentheses provided.

Answer 1

The ratio with the constant of proportionality can be determined by dividing the number of loaves of bread by the amount of flour needed for that number of loaves.

For example, for the first ratio (1, 1/2), we divide the number of loaves (1) by the amount of flour needed (1/2).

1 ÷ 1/2 = 2

So, the ratio with the constant of proportionality is (1, 2).
