When you ask "What number is halfway between 47 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=47 and Y=638.
To find the number halfway between 47 and 638, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 47 and 638 into our formula, we get:
(47 + 638)/2 = 342.5
Thus, the number halfway between 47 and 638 is 342.5.
To check that our answer is correct, we subtract 47 from 342.5 and subtract 342.5 from 638 and compare the two numbers:
342.5 - 47 = 295.5
638 - 342.5 = 295.5
As you can see, the halfway number is 295.5 higher than 47 and 295.5 lower than 638. Therefore, our halfway between answer of 342.5 above is correct.
