Final answer:
The distance between points A at -6/8 and B at -1/8 on a number line is 5/8 units.
Step-by-step explanation:
The distance between points A and B, located at -6/8 and -1/8 respectively, can be found by taking the absolute difference of their positions. Since both points are on a number line (which can be assumed because only one coordinate is given for each point), the distance is the absolute value of the difference between the two points:
|A - B| = |-6/8 - (-1/8)| = |-6/8 + 1/8| = |-5/8|
Therefore, the distance is 5/8 units.
