Understanding Equivalent Ratios through Ratio Tables

What is the primary purpose of using ratio tables?

• To compare ratios of different units

• To create complex mathematical models

• To divide ratios into smaller parts

• To organize work and solve for missing values

How do you find an equivalent ratio?

• By adding the same number to both parts of the ratio

• By subtracting the same number from both parts of the ratio

• By swapping the numerator and denominator

• By multiplying or dividing both parts of the ratio by the same number

In the boys to girls ratio example, what operation is used to find the equivalent ratio?

• Multiplication

• Division

• Subtraction

• Addition

What is the equivalent ratio to 4:6 in the dogs to cats example?

• 8:10

• 8:12

• 10:12

• 12:18

How do you determine the operation (multiply or divide) to find the missing value in a ratio table?

• By always dividing

• By always multiplying

• By guessing and checking

• By comparing the initial and final values of the ratio

When creating a ratio table from scratch, what is the first step?

• Determining the total number of items

• Comparing the items to find a ratio

• Setting up the table with headings

• Multiplying the given ratio

In the car washing scenario, how many cars does the friend wash if you wash eight?

• 12 cars

• 10 cars

• 14 cars

• 16 cars

What is the ratio of purchased songs to free songs in the final problem?

• 40 to 24

• 24 to 40

• 18 to 24

• 24 to 18

How do you find the number of songs you need to purchase to get 18 free downloads?

• By setting up a ratio table

• By guessing the number

• By dividing 18 by 2

• By multiplying 18 by 2

What is the key concept to remember when finding equivalent ratios?

• The sum of the ratios must be constant

• The difference between the ratios must increase

• The relationship between the ratios must remain the same

• The product of the ratios must be a prime number
