Halfway Between 40 and 315

When you ask "What number is halfway between 40 and 315?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=40 and Y=315.

Halfway Between Line

To find the number halfway between 40 and 315, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 315 into our formula, we get:

(40 + 315)/2 = 177.5

Thus, the number halfway between 40 and 315 is 177.5.

To check that our answer is correct, we subtract 40 from 177.5 and subtract 177.5 from 315 and compare the two numbers:

177.5 - 40 = 137.5
315 - 177.5 = 137.5

As you can see, the halfway number is 137.5 higher than 40 and 137.5 lower than 315. Therefore, our halfway between answer of 177.5 above is correct.
