Halfway Between 45 and 580

When you ask "What number is halfway between 45 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=45 and Y=580.

Halfway Between Line

To find the number halfway between 45 and 580, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 580 into our formula, we get:

(45 + 580)/2 = 312.5

Thus, the number halfway between 45 and 580 is 312.5.

To check that our answer is correct, we subtract 45 from 312.5 and subtract 312.5 from 580 and compare the two numbers:

312.5 - 45 = 267.5
580 - 312.5 = 267.5

As you can see, the halfway number is 267.5 higher than 45 and 267.5 lower than 580. Therefore, our halfway between answer of 312.5 above is correct.
