Do you feel you need to review the divisibility rules before we begin?

• Yes

• No

​Let's Review the Divisibility Rules

Multiple Choice

What is the value of the ratio 5 : 25? 

• $$\frac{2}{5}$$  

• $$\ \frac{1}{5}$$  

• $$\frac{2}{10}$$  

• $$\frac{3}{5}$$  

Multiple Choice

What is the value of the ratio 10:30?

• $$\frac{1\ }{3\ }$$  

• $$\ \frac{1}{5}$$  

• $$\frac{2}{10}$$  

• $$\frac{3}{5}$$  

Multiple Choice

What is the value of the ratio 6:10?

• $$\frac{10}{6}$$  

• $$\frac{2}{5}$$  

• $$\frac{3}{5}$$  

• $$\frac{5}{15}$$  

​Let's Review How We Can Use Ratio Tables to Make a Comparison.

​

​Strategy 1- Find a Commonality -(Remember, the value must be in the same category for each table.)

​

​Strategy 2 - Find the value of the ratio to see if you can find a commonality. If not, try extending the ratio table.

​Let's Review One together.

​Kiley and Sophia are mixing paint. Kiley's uses 4 cups of red for every 3 cups of blue paint in her mixture and Sophia uses 3 cups of red for every 2 cups of blue in her mixture.

​Which Mixture will have a stronger red tint?

​The commonality is

​Kiley and Sophia are mixing paint. Kiley's uses 4 cups of red for every 3 cups of blue paint in her mixture and Sophia uses 3 cups of red for every 2 cups of blue in her mixture.

​Which Mixture will have a stronger red tint?

​The commonality is 6 or 12​Now let's compare the amount of red paint for each. Which one has more red paint for the same amount of of blue paint?

​Which Mixture will have a stronger red tint?

​Sophia's paint has the stronger red tint because for the same amount of blue paint (6 cups), it has more red paint or for the or for the same amount of red paint (12 cups), Sophia has less red paint.

Multiple Choice

• Jadiel's recipe

• Christopher's recipe

Multiple Choice

Which chili recipe will taste spicier?

• Jadiel's Recipe will taste spicier because it has more ground beef for the same amount of chili powder. 

• Christopher's Recipe will taste spicier because it has less ground beef for the same amount of chili powder.
