Halfway Between 80 and 663

When you ask "What number is halfway between 80 and 663?" 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=663.

Halfway Between Line

To find the number halfway between 80 and 663, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 663 into our formula, we get:

(80 + 663)/2 = 371.5

Thus, the number halfway between 80 and 663 is 371.5.

To check that our answer is correct, we subtract 80 from 371.5 and subtract 371.5 from 663 and compare the two numbers:

371.5 - 80 = 291.5
663 - 371.5 = 291.5

As you can see, the halfway number is 291.5 higher than 80 and 291.5 lower than 663. Therefore, our halfway between answer of 371.5 above is correct.
