Question

Trevor asks the restaurant for the recipe for the "Boa Brownie Bites" to ensure that he is not allergic to any of its ingredients. The recipe uses 15 cups of flour for every 5 cups of sugar.

Which of the following describes a unit rate for the recipe?

The recipe needs 3 cups of flour for each cup of sugar.
The recipe needs 3 cups of sugar for each cup of flour.
The recipe needs 12 cups of sugar for each cup of flour.
The recipe needs 12 cups of flour for each cup of sugar.

Answer 1

The recipe needs 3 cups of flour for each cup of sugar.

Explanation:

This is a unit rate because it represents the amount of one unit (flour) needed for every one unit (cup of sugar). It is also a ratio because it represents the relative amount of each ingredient needed in the recipe. The unit rate helps to understand the relative proportions of the ingredients in the recipe and can be used to scale the recipe up or down as needed.
