When you ask "What number is halfway between 47 and 316?" 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=316.

To find the number halfway between 47 and 316, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 47 and 316 into our formula, we get:
(47 + 316)/2 = 181.5
Thus, the number halfway between 47 and 316 is 181.5.
To check that our answer is correct, we subtract 47 from 181.5 and subtract 181.5 from 316 and compare the two numbers:
181.5 - 47 = 134.5
316 - 181.5 = 134.5
As you can see, the halfway number is 134.5 higher than 47 and 134.5 lower than 316. Therefore, our halfway between answer of 181.5 above is correct.
