When you ask "What number is halfway between 9 and 111?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=9 and Y=111.
To find the number halfway between 9 and 111, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 9 and 111 into our formula, we get:
(9 + 111)/2 = 60
Thus, the number halfway between 9 and 111 is 60.
To check that our answer is correct, we subtract 9 from 60 and subtract 60 from 111 and compare the two numbers:
60 - 9 = 51
111 - 60 = 51
As you can see, the halfway number is 51 higher than 9 and 51 lower than 111. Therefore, our halfway between answer of 60 above is correct.
