Halfway Between 80 and 805

When you ask "What number is halfway between 80 and 805?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=80 and Y=805.

Halfway Between Line

To find the number halfway between 80 and 805, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 805 into our formula, we get:

(80 + 805)/2 = 442.5

Thus, the number halfway between 80 and 805 is 442.5.

To check that our answer is correct, we subtract 80 from 442.5 and subtract 442.5 from 805 and compare the two numbers:

442.5 - 80 = 362.5
805 - 442.5 = 362.5

As you can see, the halfway number is 362.5 higher than 80 and 362.5 lower than 805. Therefore, our halfway between answer of 442.5 above is correct.
