When you ask "What number is halfway between 99 and 408?" 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=408.
To find the number halfway between 99 and 408, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 99 and 408 into our formula, we get:
(99 + 408)/2 = 253.5
Thus, the number halfway between 99 and 408 is 253.5.
To check that our answer is correct, we subtract 99 from 253.5 and subtract 253.5 from 408 and compare the two numbers:
253.5 - 99 = 154.5
408 - 253.5 = 154.5
As you can see, the halfway number is 154.5 higher than 99 and 154.5 lower than 408. Therefore, our halfway between answer of 253.5 above is correct.
