Question

On a number line what is the distance between -3/7 -2/3 

Answer 1

-3/7, -2/3

Lowest common denominator is 21. 

-9/21, -14/21

 

Since distance is always considered positive, 

take the absolute value of the difference.

 

|-14/21 - (-9/21)| = |-5/21| = 5/21

 

Answer 2

Distance between two points in this case is the absolute value of difference between these two points: |-2/3-(-3/7)|=|3/7-2/3|=|9-14/21|=|-5/21|=5/21
