A **number line** represents the value of a number as a distance from zero.

On a horizontal number line, **positive** numbers are to the right

of zero, and **negative** numbers are to the left of zero.

A number line can represent a **fraction** or **decimal** by dividing

the space between two consecutive integers into equal parts.

First, locate -2 on the number line.

The ticks on the number line are 1 unit apart, so -2 is 2 tick marks to the left of 0.

Next, divide the space between 0 and 1 into three equal sections, divide the space between 1 and 2 into two equal sections, and divide the space between 2 and 3 into four equal sections.

Then, locate $\frac{2}{3}$, $1\frac{1}{2}$, and 2.75 on the number line.
