When you ask "What number is halfway between 47 and 270?" 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=270.

To find the number halfway between 47 and 270, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 47 and 270 into our formula, we get:
(47 + 270)/2 = 158.5
Thus, the number halfway between 47 and 270 is 158.5.
To check that our answer is correct, we subtract 47 from 158.5 and subtract 158.5 from 270 and compare the two numbers:
158.5 - 47 = 111.5
270 - 158.5 = 111.5
As you can see, the halfway number is 111.5 higher than 47 and 111.5 lower than 270. Therefore, our halfway between answer of 158.5 above is correct.
