Halfway Between 80 and 879

When you ask "What number is halfway between 80 and 879?" 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=879.

Halfway Between Line

To find the number halfway between 80 and 879, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 879 into our formula, we get:

(80 + 879)/2 = 479.5

Thus, the number halfway between 80 and 879 is 479.5.

To check that our answer is correct, we subtract 80 from 479.5 and subtract 479.5 from 879 and compare the two numbers:

479.5 - 80 = 399.5
879 - 479.5 = 399.5

As you can see, the halfway number is 399.5 higher than 80 and 399.5 lower than 879. Therefore, our halfway between answer of 479.5 above is correct.
