Halfway Between 48 and 645

When you ask "What number is halfway between 48 and 645?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=48 and Y=645.

Halfway Between Line

To find the number halfway between 48 and 645, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 48 and 645 into our formula, we get:

(48 + 645)/2 = 346.5

Thus, the number halfway between 48 and 645 is 346.5.

To check that our answer is correct, we subtract 48 from 346.5 and subtract 346.5 from 645 and compare the two numbers:

346.5 - 48 = 298.5
645 - 346.5 = 298.5

As you can see, the halfway number is 298.5 higher than 48 and 298.5 lower than 645. Therefore, our halfway between answer of 346.5 above is correct.
