Module 1 Lesson 5

In a rice recipe, a ratio that relates the number of cups of water to the number of cups of rice is 2:1. What is the ratio of cups of rice to cups of water?

• 1:2

• 2:1

• 1:1

• 3:1

In a rice recipe, a ratio that relates the number of cups of water to the number of cups of rice is 2:1. How many cups of water should be mixed with 4 cups of rice?

• 2 cups

• 4 cups

The tape diagram shows that the ratio 4:3 is equivalent to the ratio 8:6. Draw a tape diagram to show that the ratio 4:3 is equivalent to the ratio 20:15.

The tape diagram shows that the ratio 4:3 is equivalent to the ratio 8:6. Yuna thinks that the ratio 4:3 is equivalent to the ratio 10:9 because 6 + 4 = 10 and 6 + 3 = 9. What is Yuna’s mistake? What can she do to find an equivalent ratio?

• Yuna added the numbers instead of multiplying them.

• Yuna subtracted the numbers instead of adding them.

• Yuna divided the numbers instead of multiplying them.

• Yuna multiplied the numbers instead of adding them.

Consider the ratios 3:5 and 21:D.

What must D be for the ratios to be equivalent?

• 30

• 35

• 25

• 40

The tape diagram represents the ratio of the number of free throws made to the number of free throws missed at a basketball game.

If this pattern continues and 12 free throws are made, what is the total number of free throw

attempts in the game?

• 48
• 36
• 24
• 22

For every 6 free throws that are made, 5 are missed. If this pattern continues and there are a total of 33 free throw attempts in the game, how many free throws are made? How many free throws are missed?

• 18 made, 15 missed

• 15 made, 18 missed

• 25 made, 8 missed

• 10 made, 23 missed

A sidewalk chalk recipe calls for 1 ounce of cornstarch for every 3 ounces of baking soda.

Draw a tape diagram that represents the ratio of the number of ounces of cornstarch to the

number of ounces of baking soda.

A sidewalk chalk recipe calls for 1 ounce of cornstarch for every 3 ounces of baking soda.

How many ounces of cornstarch and how many ounces of baking soda are in a total of 32 ounces of sidewalk chalk?

• 16 ounces of cornstarch and 16 ounces of baking soda

• 20 ounces of cornstarch and 12 ounces of baking soda

• 10 ounces of cornstarch and 22 ounces of baking soda

• 8 ounces of cornstarch and 24 ounces of baking soda
