Halfway Between 30 and 45

When you ask "What number is halfway between 30 and 45?" 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=45.

Halfway Between Line

To find the number halfway between 30 and 45, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 45 into our formula, we get:

(30 + 45)/2 = 37.5

Thus, the number halfway between 30 and 45 is 37.5.

To check that our answer is correct, we subtract 30 from 37.5 and subtract 37.5 from 45 and compare the two numbers:

37.5 - 30 = 7.5
45 - 37.5 = 7.5

As you can see, the halfway number is 7.5 higher than 30 and 7.5 lower than 45. Therefore, our halfway between answer of 37.5 above is correct.
