When you ask "What number is halfway between 99 and 887?" 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=887.
To find the number halfway between 99 and 887, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 99 and 887 into our formula, we get:
(99 + 887)/2 = 493
Thus, the number halfway between 99 and 887 is 493.
To check that our answer is correct, we subtract 99 from 493 and subtract 493 from 887 and compare the two numbers:
493 - 99 = 394
887 - 493 = 394
As you can see, the halfway number is 394 higher than 99 and 394 lower than 887. Therefore, our halfway between answer of 493 above is correct.
