Halfway Between 80 and 543

When you ask "What number is halfway between 80 and 543?" 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=543.

Halfway Between Line

To find the number halfway between 80 and 543, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 543 into our formula, we get:

(80 + 543)/2 = 311.5

Thus, the number halfway between 80 and 543 is 311.5.

To check that our answer is correct, we subtract 80 from 311.5 and subtract 311.5 from 543 and compare the two numbers:

311.5 - 80 = 231.5
543 - 311.5 = 231.5

As you can see, the halfway number is 231.5 higher than 80 and 231.5 lower than 543. Therefore, our halfway between answer of 311.5 above is correct.
