Answer:
3 units
4 1/2 or - 1 1/2
Step-by-step explanation:
Given that :
Value of n is a distance of 3 units from 1 1/2 on a number line.
Recall that a number line may be divided into two parts that is the left and righmosr portions with 0 as the mid point.
Hence a value of 3 units from 1 1/2 may be to the right (positive) or to the left(negative side of the line).
Therefore :
1 1/2 + 3 = 4 1/ 2
1 1/2 - 3 = - 1 1/2
The value n will result in a distance of 3 units in either way and could be either 4 1/2 or - 1 1/2
