Halfway Between 9 and 580

When you ask "What number is halfway between 9 and 580?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=9 and Y=580.

Halfway Between Line

To find the number halfway between 9 and 580, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 580 into our formula, we get:

(9 + 580)/2 = 294.5

Thus, the number halfway between 9 and 580 is 294.5.

To check that our answer is correct, we subtract 9 from 294.5 and subtract 294.5 from 580 and compare the two numbers:

294.5 - 9 = 285.5
580 - 294.5 = 285.5

As you can see, the halfway number is 285.5 higher than 9 and 285.5 lower than 580. Therefore, our halfway between answer of 294.5 above is correct.
