Halfway Between 40 and 51

When you ask "What number is halfway between 40 and 51?" 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=51.

Halfway Between Line

To find the number halfway between 40 and 51, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 51 into our formula, we get:

(40 + 51)/2 = 45.5

Thus, the number halfway between 40 and 51 is 45.5.

To check that our answer is correct, we subtract 40 from 45.5 and subtract 45.5 from 51 and compare the two numbers:

45.5 - 40 = 5.5
51 - 45.5 = 5.5

As you can see, the halfway number is 5.5 higher than 40 and 5.5 lower than 51. Therefore, our halfway between answer of 45.5 above is correct.
