Halfway Between 100 and 115




When you ask "What number is halfway between 100 and 115?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=100 and Y=115.



To find the number halfway between 100 and 115, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 115 into our formula, we get:

(100 + 115)/2 = 107.5

Thus, the number halfway between 100 and 115 is 107.5.


To check that our answer is correct, we subtract 100 from 107.5 and subtract 107.5 from 115 and compare the two numbers:

107.5 - 100 = 7.5
115 - 107.5 = 7.5

As you can see, the halfway number is 7.5 higher than 100 and 7.5 lower than 115. Therefore, our halfway between answer of 107.5 above is correct.
