When you ask "What number is halfway between 99 and 812?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=99 and Y=812.
To find the number halfway between 99 and 812, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 99 and 812 into our formula, we get:
(99 + 812)/2 = 455.5
Thus, the number halfway between 99 and 812 is 455.5.
To check that our answer is correct, we subtract 99 from 455.5 and subtract 455.5 from 812 and compare the two numbers:
455.5 - 99 = 356.5
812 - 455.5 = 356.5
As you can see, the halfway number is 356.5 higher than 99 and 356.5 lower than 812. Therefore, our halfway between answer of 455.5 above is correct.
