Halfway Between 87 and 180

When you ask "What number is halfway between 87 and 180?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=87 and Y=180.

Halfway Between Line

To find the number halfway between 87 and 180, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 87 and 180 into our formula, we get:

(87 + 180)/2 = 133.5

Thus, the number halfway between 87 and 180 is 133.5.

To check that our answer is correct, we subtract 87 from 133.5 and subtract 133.5 from 180 and compare the two numbers:

133.5 - 87 = 46.5
180 - 133.5 = 46.5

As you can see, the halfway number is 46.5 higher than 87 and 46.5 lower than 180. Therefore, our halfway between answer of 133.5 above is correct.
