Halfway Between 80 and 877

When you ask "What number is halfway between 80 and 877?" 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=877.

Halfway Between Line

To find the number halfway between 80 and 877, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 877 into our formula, we get:

(80 + 877)/2 = 478.5

Thus, the number halfway between 80 and 877 is 478.5.

To check that our answer is correct, we subtract 80 from 478.5 and subtract 478.5 from 877 and compare the two numbers:

478.5 - 80 = 398.5
877 - 478.5 = 398.5

As you can see, the halfway number is 398.5 higher than 80 and 398.5 lower than 877. Therefore, our halfway between answer of 478.5 above is correct.
