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

The distance between these two is 5/21.

In order to find the distance between two points on a number line, subtract one from the other. In this case, we'll need to give them common denominators.

-2/3 - -3/7

-14/21 + 9/21

-5/21

Because our answer is negative, we take the absolute value. Distance is usually expressed as a positive.

5/21

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
