When you ask "What number is halfway between 47 and 143?" 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=143.
To find the number halfway between 47 and 143, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 47 and 143 into our formula, we get:
(47 + 143)/2 = 95
Thus, the number halfway between 47 and 143 is 95.
To check that our answer is correct, we subtract 47 from 95 and subtract 95 from 143 and compare the two numbers:
95 - 47 = 48
143 - 95 = 48
As you can see, the halfway number is 48 higher than 47 and 48 lower than 143. Therefore, our halfway between answer of 95 above is correct.
