When you ask "What number is halfway between 47 and 988?" 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=988.
To find the number halfway between 47 and 988, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 47 and 988 into our formula, we get:
(47 + 988)/2 = 517.5
Thus, the number halfway between 47 and 988 is 517.5.
To check that our answer is correct, we subtract 47 from 517.5 and subtract 517.5 from 988 and compare the two numbers:
517.5 - 47 = 470.5
988 - 517.5 = 470.5
As you can see, the halfway number is 470.5 higher than 47 and 470.5 lower than 988. Therefore, our halfway between answer of 517.5 above is correct.
