When you ask "What number is halfway between 7 and 638?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=7 and Y=638.
To find the number halfway between 7 and 638, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 7 and 638 into our formula, we get:
(7 + 638)/2 = 322.5
Thus, the number halfway between 7 and 638 is 322.5.
To check that our answer is correct, we subtract 7 from 322.5 and subtract 322.5 from 638 and compare the two numbers:
322.5 - 7 = 315.5
638 - 322.5 = 315.5
As you can see, the halfway number is 315.5 higher than 7 and 315.5 lower than 638. Therefore, our halfway between answer of 322.5 above is correct.
