Answer: The answer is 12.
Step-by-step explanation: Given that a point 'x' is lying at
on the number line. Another point 'y' is also lying at the same distance from 0 but has a numerator of 8. We are to find the denominator of 'y'.
Since 'x' is lying at
on the number line so its distance from 0 will be

Let the denominator of 'y' be p, then its distance from 0 will be

According to the given information, we must have

Thus, the denominator will be 12.
