Halfway Between 80 and 515

When you ask "What number is halfway between 80 and 515?" 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=515.

Halfway Between Line

To find the number halfway between 80 and 515, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 515 into our formula, we get:

(80 + 515)/2 = 297.5

Thus, the number halfway between 80 and 515 is 297.5.

To check that our answer is correct, we subtract 80 from 297.5 and subtract 297.5 from 515 and compare the two numbers:

297.5 - 80 = 217.5
515 - 297.5 = 217.5

As you can see, the halfway number is 217.5 higher than 80 and 217.5 lower than 515. Therefore, our halfway between answer of 297.5 above is correct.
