Halfway Between 9 and 118

When you ask "What number is halfway between 9 and 118?" 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=118.

Halfway Between Line

To find the number halfway between 9 and 118, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 118 into our formula, we get:

(9 + 118)/2 = 63.5

Thus, the number halfway between 9 and 118 is 63.5.

To check that our answer is correct, we subtract 9 from 63.5 and subtract 63.5 from 118 and compare the two numbers:

63.5 - 9 = 54.5
118 - 63.5 = 54.5

As you can see, the halfway number is 54.5 higher than 9 and 54.5 lower than 118. Therefore, our halfway between answer of 63.5 above is correct.
