Halfway Between 27 and 36

When you ask "What number is halfway between 27 and 36?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=27 and Y=36.

Halfway Between Line

To find the number halfway between 27 and 36, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 27 and 36 into our formula, we get:

(27 + 36)/2 = 31.5

Thus, the number halfway between 27 and 36 is 31.5.

To check that our answer is correct, we subtract 27 from 31.5 and subtract 31.5 from 36 and compare the two numbers:

31.5 - 27 = 4.5
36 - 31.5 = 4.5

As you can see, the halfway number is 4.5 higher than 27 and 4.5 lower than 36. Therefore, our halfway between answer of 31.5 above is correct.
