Question

Point x is at 2/3 on a number line on the same number line , point y is the same distance from 0 as point x but has numerator of 8 what is the denominator of the fraction at point y draw number line to model the problem

Answer 1

Explanation:

Set this up as a proportion, leaving our unknown in the denominator of the second ratio:

`(2)/(3)=(8)/(x)`

Cross multiply to solve for x:

2x = 24 so

x = 12

But if it on the other side of 0, it has to be negative. So the ratio is -8/12 which reduces to -2/3.
