Exploring Ratio and Rate Tables

This video tutorial explains the concepts of ratios and rates, highlighting the differences between them. It covers how to fill in incomplete ratio and rate tables by calculating unit ratios and rates. The video provides step-by-step examples for both ratio and rate tables, demonstrating how to use multiplication and division to find equivalent values. The tutorial concludes with a summary of the methods used to ensure accuracy in filling these tables.

What is a ratio?

• A type of fraction

• A comparison of two quantities with different units

• A comparison of two quantities with the same unit

• A type of percentage

Which of the following is an example of a rate?

• Students to teachers

• Pencils to erasers

• Miles per hour

• Cats to dogs

What is a unit ratio?

• A ratio that compares different units

• A ratio that is always greater than one

• A ratio where one of the quantities is one

• A ratio where both quantities are the same

How do you find a unit ratio for one student if the original ratio is 36 students to 4 teachers?

• Divide both quantities by 4

• Multiply both quantities by 4

• Divide both quantities by 36

• Multiply both quantities by 36

If the ratio of students to teachers is 36 to 4, what is the unit ratio per one teacher?

• 4 students to 1 teacher

• 1 student to 4 teachers

• 9 students to 1 teacher

• 1 student to 9 teachers

In a ratio table, what should you do if you need to find the number of students for 20 teachers?

• Divide the unit ratio by 20

• Divide the number of students by 20

• Multiply the unit ratio by 20

• Multiply the number of students by 20

What is the rate if Lucas finishes 18 practice problems in 6 minutes?

• 1 problem per minute

• 18 problems per minute

• 6 problems per minute

• 3 problems per minute

How many problems can Lucas complete in 1 minute if he finishes 18 problems in 6 minutes?

• 1 problem

• 2 problems

• 3 problems

• 6 problems

If Lucas can complete 3 problems in 1 minute, how many problems can he complete in 5 minutes?

• 20 problems

• 15 problems

• 25 problems

• 10 problems

How can you check if the values in a rate table are correct?

• By adding the values diagonally

• By subtracting the values diagonally

• By multiplying the values diagonally

• By dividing the values diagonally
