When you ask "What number is halfway between 87 and 216?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=87 and Y=216.
To find the number halfway between 87 and 216, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 87 and 216 into our formula, we get:
(87 + 216)/2 = 151.5
Thus, the number halfway between 87 and 216 is 151.5.
To check that our answer is correct, we subtract 87 from 151.5 and subtract 151.5 from 216 and compare the two numbers:
151.5 - 87 = 64.5
216 - 151.5 = 64.5
As you can see, the halfway number is 64.5 higher than 87 and 64.5 lower than 216. Therefore, our halfway between answer of 151.5 above is correct.
