Halfway Between 12 and 27

When you ask "What number is halfway between 12 and 27?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=12 and Y=27.

Halfway Between Line

To find the number halfway between 12 and 27, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 12 and 27 into our formula, we get:

(12 + 27)/2 = 19.5

Thus, the number halfway between 12 and 27 is 19.5.

To check that our answer is correct, we subtract 12 from 19.5 and subtract 19.5 from 27 and compare the two numbers:

19.5 - 12 = 7.5
27 - 19.5 = 7.5

As you can see, the halfway number is 7.5 higher than 12 and 7.5 lower than 27. Therefore, our halfway between answer of 19.5 above is correct.
