Halfway Between 47 and 647

When you ask "What number is halfway between 47 and 647?" 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=647.

Halfway Between Line

To find the number halfway between 47 and 647, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 47 and 647 into our formula, we get:

(47 + 647)/2 = 347

Thus, the number halfway between 47 and 647 is 347.

To check that our answer is correct, we subtract 47 from 347 and subtract 347 from 647 and compare the two numbers:

347 - 47 = 300
647 - 347 = 300

As you can see, the halfway number is 300 higher than 47 and 300 lower than 647. Therefore, our halfway between answer of 347 above is correct.
