When you ask "What number is halfway between 30 and 151?" 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=151.
To find the number halfway between 30 and 151, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 30 and 151 into our formula, we get:
(30 + 151)/2 = 90.5
Thus, the number halfway between 30 and 151 is 90.5.
To check that our answer is correct, we subtract 30 from 90.5 and subtract 90.5 from 151 and compare the two numbers:
90.5 - 30 = 60.5
151 - 90.5 = 60.5
As you can see, the halfway number is 60.5 higher than 30 and 60.5 lower than 151. Therefore, our halfway between answer of 90.5 above is correct.
