Halfway Between 80 and 878

When you ask "What number is halfway between 80 and 878?" 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=878.

Halfway Between Line

To find the number halfway between 80 and 878, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 878 into our formula, we get:

(80 + 878)/2 = 479

Thus, the number halfway between 80 and 878 is 479.

To check that our answer is correct, we subtract 80 from 479 and subtract 479 from 878 and compare the two numbers:

479 - 80 = 399
878 - 479 = 399

As you can see, the halfway number is 399 higher than 80 and 399 lower than 878. Therefore, our halfway between answer of 479 above is correct.
