Halfway Between 30 and 47

When you ask "What number is halfway between 30 and 47?" 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=47.

Halfway Between Line

To find the number halfway between 30 and 47, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 47 into our formula, we get:

(30 + 47)/2 = 38.5

Thus, the number halfway between 30 and 47 is 38.5.

To check that our answer is correct, we subtract 30 from 38.5 and subtract 38.5 from 47 and compare the two numbers:

38.5 - 30 = 8.5
47 - 38.5 = 8.5

As you can see, the halfway number is 8.5 higher than 30 and 8.5 lower than 47. Therefore, our halfway between answer of 38.5 above is correct.
