Question

Match the positions on the number line with the numbers they represent.

1.8
2.2
-2.2
-1.8

Position on the Number Line
A) 1.8 units to the right of 0 on horizontal number line
B) 2.2 units to the left of 0 on horizontal number line
C) 1.8 units above 0 on vertical number line
D) 2.2 units below 0 on vertical number line

Answer 1

The numbers 1.8 and -2.2 match with positions A (to the right on a horizontal line) and B (to the left on a horizontal line) respectively. The number 2.2 matches with position D (below zero on a vertical line). There is no provided position match for -1.8.

Step-by-step explanation:

Let's match the positions on the number line with the numbers they represent:

• Number 1.8 matches with Position A) because 1.8 is a positive number, indicating it is on the right side of zero on a horizontal number line.
• Number -2.2 matches with Position B) because -2.2 is a negative number, which signifies it is on the left side of zero on a horizontal number line.
• Number 2.2 matches with Position D) as it is positive and represents movement below the origin in a vertical number line with a positive measure, indicative of downward movement.
• Number -1.8 does not have a matching position in the options provided since it would represent movement to the left or downward, and there is no option for -1.8 units below 0 on the vertical number line or -1.8 units to the left of 0 on the horizontal number line.

Therefore, the correct matches are:

1.8 matches with Position A)

-2.2 matches with Position B)

2.2 matches with Position D)
However, we have no match for -1.8 based on the positions provided.
