Halfway Between 80 and 939

When you ask "What number is halfway between 80 and 939?" 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=939.

Halfway Between Line

To find the number halfway between 80 and 939, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 939 into our formula, we get:

(80 + 939)/2 = 509.5

Thus, the number halfway between 80 and 939 is 509.5.

To check that our answer is correct, we subtract 80 from 509.5 and subtract 509.5 from 939 and compare the two numbers:

509.5 - 80 = 429.5
939 - 509.5 = 429.5

As you can see, the halfway number is 429.5 higher than 80 and 429.5 lower than 939. Therefore, our halfway between answer of 509.5 above is correct.
