Exploring the Double Number Line Concept

What is the primary purpose of a double number line?

• To visualize equivalent ratios

• To compare fractions

• To solve algebraic equations

• To measure distances

In the example with Meghan, how many hours did it take her to complete three pages of math homework?

• One hour

• Two hours

• Three hours

• Four hours

What is the first step in creating a double number line?

• Mark the ratio

• Multiply the ratio

• Label the lines

• Draw two horizontal lines

When extending the double number line for Meghan's problem, what is the ratio of hours to pages?

• 4:5

• 3:4

• 2:3

• 1:2

How many pages of math homework will Meghan complete in eight hours?

• 16 pages

• 10 pages

• 12 pages

• 14 pages

In the example with Bob, how many quarters did he have for every seven dimes?

• Four quarters

• Three quarters

• Six quarters

• Five quarters

What is the initial ratio of quarters to dimes in Bob's piggy bank?

• 3:5

• 4:6

• 5:7

• 6:8

How many dimes does Bob have if he has 20 quarters?

• 28 dimes

• 30 dimes

• 26 dimes

• 24 dimes

What is the next step after marking the initial ratio on the double number line?

• Add the values

• Subtract the values

• Divide the ratio

• Multiply the ratio

How do you determine the number of dimes Bob has using the double number line?

• By extending the number line to 20 quarters

• By multiplying the quarters by the ratio

• By adding the quarters and dimes

• By dividing the quarters by the ratio
