When you ask "What number is halfway between 30 and 315?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=30 and Y=315.
To find the number halfway between 30 and 315, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 30 and 315 into our formula, we get:
(30 + 315)/2 = 172.5
Thus, the number halfway between 30 and 315 is 172.5.
To check that our answer is correct, we subtract 30 from 172.5 and subtract 172.5 from 315 and compare the two numbers:
172.5 - 30 = 142.5
315 - 172.5 = 142.5
As you can see, the halfway number is 142.5 higher than 30 and 142.5 lower than 315. Therefore, our halfway between answer of 172.5 above is correct.
