Halfway Between 45 and 660

When you ask "What number is halfway between 45 and 660?" 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=660.

Halfway Between Line

To find the number halfway between 45 and 660, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 660 into our formula, we get:

(45 + 660)/2 = 352.5

Thus, the number halfway between 45 and 660 is 352.5.

To check that our answer is correct, we subtract 45 from 352.5 and subtract 352.5 from 660 and compare the two numbers:

352.5 - 45 = 307.5
660 - 352.5 = 307.5

As you can see, the halfway number is 307.5 higher than 45 and 307.5 lower than 660. Therefore, our halfway between answer of 352.5 above is correct.
