Plotting Rational Numbers on a Number Line

The video tutorial explains how to plot rational numbers on a number line by first determining the number of spaces between 0 and 1. It covers converting fractions to have a common denominator of 4, and demonstrates plotting both negative and positive fractions. The tutorial also includes advanced techniques for plotting fractions, emphasizing the importance of understanding the movement direction based on the sign of the fraction.

• 5

• 4

• 3

• 2

What should be the common denominator when there are 4 spaces between 0 and 1?

• 2

If you start at -2 and the numerator is -2, how many spaces do you move and in which direction?

• 3 spaces to the right

• 2 spaces to the right

• 3 spaces to the left

• 2 spaces to the left

For the fraction 1 and 3/4, how many spaces do you move from 1?

• 4

When converting 1/2 to a denominator of 4, what is the resulting numerator?

• 4

• 1

• 3

• 2

If you start at -1 and the numerator is -2, where do you end up?

• -1

• -2

• -3

• -4

For a fraction with a positive numerator, in which direction do you move on the number line?

• Down

• Up

• Right

• Left

If you start at -1 and the numerator is -3, how many spaces do you move and in which direction?

• 2 spaces to the right

• 3 spaces to the left

• 3 spaces to the right

• 2 spaces to the left

When converting 5/2 to a denominator of 4, what is the resulting numerator?

• 10
