Halfway Between 47 and 645

When you ask "What number is halfway between 47 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=47 and Y=645.

Halfway Between Line

To find the number halfway between 47 and 645, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 47 and 645 into our formula, we get:

(47 + 645)/2 = 346

Thus, the number halfway between 47 and 645 is 346.

To check that our answer is correct, we subtract 47 from 346 and subtract 346 from 645 and compare the two numbers:

346 - 47 = 299
645 - 346 = 299

As you can see, the halfway number is 299 higher than 47 and 299 lower than 645. Therefore, our halfway between answer of 346 above is correct.
