Reading Ratio Relationships Practice

Reading Ratio Relationships Practice

by Mr. Luczak

​Tomorrow, we will use this template to help us organize information.

Let's Practice understanding what these questions are asking for.

​What are we comparing?

​There are 49 empty seats and 1 occupied seat on an airplane. What is the ratio of the number of empty seats to the number of occupied seats?

​

​Our goal is to determine what quanities we will compare in our ratio.

​

​Remember, Order Matters!

​What are we comparing?

​There are 49 empty seats and 1 occupied seat on an airplane. What is the ratio of the number of empty seats to the number of occupied seats?

​

​Notice the second sentence. It's asking for the ratio of ___ to ___

​

​The first quantity is in red, the second quantity is in blue

​

​So we are comparing the # of empty seats to the # of occupied seats

Multiple Choice

There are 49 empty seats and 1 occupied seat on an airplane. What is the ratio of the number of empty seats to the number of occupied seats?

What is the correct order of the quantities being compared in the ratio?

• # of empty seats to # of occupied seats

• # of occupied seats to # of empty seats

• # of empty seats to the total # of seats

• # of occupied seats to total # of seats

Multiple Choice

A movie theater sold 8 child tickets. The other 42 tickets it sold were adult tickets. What is the ratio of the number of child tickets to the total number of tickets?

What is the correct order of the quantities being compared in the ratio?

• # of child tickets to # of adult tickets

• # of adult tickets to # of child tickets

• # of child tickets to the total # of tickets

• # of adult tickets to total # of tickets

Multiple Choice

22 of the tables at Winston's Italian Restaurant are full and the other 18 tables are empty. What is the ratio of the number of full tables to the number of empty tables?

What is the correct order of the quantities being compared in the ratio?

• # of empty tables to # of full tables

• # of full tables to # of empty tables

• # of empty tables to the total # of tables

• # of full tables to total # of tables

Multiple Choice

In the auditorium there are 37 red chairs and 13 blue chairs. What is the ratio of the number of blue chairs to the number of red chairs?

What is the correct order of the quantities being compared in the ratio?

• # of red chairs to # of blue chairs

• # of blue chairs to # of red chairs

• # of red chairs to the total # of chairs

• # of blue chairs to total # of chairs

Multiple Choice

There are 26 empty parking spots and 24 full parking spots in the parking garage. What is the ratio of the number of empty parking spots to the total number of parking spots?

What is the correct order of the quantities being compared in the ratio?

• # of empty spots to # of adult tickets

• # of full spots to # of empty spots

• # of full spots to the total # of parking spots

• # of empty spots to total # of parking spots

Multiple Choice

There are 3 female teachers and 22 male teachers at Leah's high school. What is the ratio of the total number of teachers to the number of male teachers?

What is the correct order of the quantities being compared in the ratio?

• # of male teachers to # of female teachers

• # of female teachers to # of male teachers

• the total # of teachers to # of male teachers

• # of male teachers to total # of teachers

Now let's look at what type of ratio we have: Part to Part or Part to Whole

​When you know the quantities being compared, it's easy to determine what type of ratio it is

​ For example, if the ratio is comparing # of empty parking spaces to the # of total parking spaces, this would be a part to whole ratio because we're comparing the part of the parking spaces that are empty to the whole amount of parking spaces.

Multiple Choice

 if our ratio is comparing # of full spots to the total # of parking spots

then what type of ratio do we have?

• Part to part

• Part to whole

Multiple Choice

 if our ratio is comparing # of empty seats to # of occupied seats

then what type of ratio do we have?

• Part to part

• Part to whole

Multiple Choice

 if our ratio is comparing # of blue chairs to # of red chairs

then what type of ratio do we have?

• Part to part

• Part to whole

Multiple Choice

 if our ratio is comparing # of child tickets to the total # of tickets

then what type of ratio do we have?

• Part to part

• Part to whole

Multiple Choice

 if our ratio is comparing # of full tables to # of empty tables

then what type of ratio do we have?

• Part to part

• Part to whole

Multiple Choice

 if our ratio is comparing the total # of teachers to # of male teachers

then what type of ratio do we have?

• Part to part

• Part to whole

​If we pay close attention to the Quantities being compared, the rest of the chart will be easy to fill out.
