Number_line

There are TWO units between -2 and 0, and there are SEVEN units between 0 and 7. Together, there are NINE units between them.

Example Question #41 : Ged Math

On a number line, which of the following is the greatest distance?

The distance between -3 and 0.

The distance between -1 and 2.

The distance between -2 and 2.

Possible Answers:

The distance between -1 and 2.

The distance between -3 and 0.

All distances are equal.

The distance between -2 and 2.

Correct answer:

The distance between -2 and 2.

Explanation:

On a number line, the negative numbers lie to the left of zero and positive numbers lie to the right. To visualize the distance between numbers, look at the units:

Number_line2

-3 and 0 are 3 units apart.

-1 and 2 are 3 units apart

-2 and 2 are 4 units apart. This is the greatest distance.

Example Question #1 : Number Lines

The distance between 1 and 7.

All distances are equal.

The distance between -2 and 5.

 

The distance between -2 and 1.

Correct answer:

The distance between -2 and 5.

 

Explanation:

Looking at a number line, you can visualize the distance between positive and negative numbers:

Number_line3

There are THREE units between -2 and 1

There are SIX units between 1 and 7.

There are SEVEN units between -2 and 5, so this is the greatest distance.
