Halfway Between 9 and 478

When you ask "What number is halfway between 9 and 478?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=9 and Y=478.

Halfway Between Line

To find the number halfway between 9 and 478, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 478 into our formula, we get:

(9 + 478)/2 = 243.5

Thus, the number halfway between 9 and 478 is 243.5.

To check that our answer is correct, we subtract 9 from 243.5 and subtract 243.5 from 478 and compare the two numbers:

243.5 - 9 = 234.5
478 - 243.5 = 234.5

As you can see, the halfway number is 234.5 higher than 9 and 234.5 lower than 478. Therefore, our halfway between answer of 243.5 above is correct.
