Halfway Between 80 and 557

When you ask "What number is halfway between 80 and 557?" 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=557.

Halfway Between Line

To find the number halfway between 80 and 557, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 557 into our formula, we get:

(80 + 557)/2 = 318.5

Thus, the number halfway between 80 and 557 is 318.5.

To check that our answer is correct, we subtract 80 from 318.5 and subtract 318.5 from 557 and compare the two numbers:

318.5 - 80 = 238.5
557 - 318.5 = 238.5

As you can see, the halfway number is 238.5 higher than 80 and 238.5 lower than 557. Therefore, our halfway between answer of 318.5 above is correct.
