Halfway Between 45 and 108

When you ask "What number is halfway between 45 and 108?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=45 and Y=108.

Halfway Between Line

To find the number halfway between 45 and 108, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 108 into our formula, we get:

(45 + 108)/2 = 76.5

Thus, the number halfway between 45 and 108 is 76.5.

To check that our answer is correct, we subtract 45 from 76.5 and subtract 76.5 from 108 and compare the two numbers:

76.5 - 45 = 31.5
108 - 76.5 = 31.5

As you can see, the halfway number is 31.5 higher than 45 and 31.5 lower than 108. Therefore, our halfway between answer of 76.5 above is correct.
