When you ask "What number is halfway between 7 and 480?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=7 and Y=480.
To find the number halfway between 7 and 480, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 7 and 480 into our formula, we get:
(7 + 480)/2 = 243.5
Thus, the number halfway between 7 and 480 is 243.5.
To check that our answer is correct, we subtract 7 from 243.5 and subtract 243.5 from 480 and compare the two numbers:
243.5 - 7 = 236.5
480 - 243.5 = 236.5
As you can see, the halfway number is 236.5 higher than 7 and 236.5 lower than 480. Therefore, our halfway between answer of 243.5 above is correct.
