Halfway Between 80 and 555

When you ask "What number is halfway between 80 and 555?" 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=555.

Halfway Between Line

To find the number halfway between 80 and 555, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 555 into our formula, we get:

(80 + 555)/2 = 317.5

Thus, the number halfway between 80 and 555 is 317.5.

To check that our answer is correct, we subtract 80 from 317.5 and subtract 317.5 from 555 and compare the two numbers:

317.5 - 80 = 237.5
555 - 317.5 = 237.5

As you can see, the halfway number is 237.5 higher than 80 and 237.5 lower than 555. Therefore, our halfway between answer of 317.5 above is correct.
