Halfway Between 9 and 9

When you ask "What number is halfway between 9 and 9?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=9 and Y=9.

Halfway Between Line

To find the number halfway between 9 and 9, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 9 into our formula, we get:

(9 + 9)/2 = 9

Thus, the number halfway between 9 and 9 is 9.

To check that our answer is correct, we subtract 9 from 9 and subtract 9 from 9 and compare the two numbers:

9 - 9 = 0
9 - 9 = 0

As you can see, the halfway number is 0 higher than 9 and 0 lower than 9. Therefore, our halfway between answer of 9 above is correct.
