When you ask "What number is halfway between 21 and 936?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=21 and Y=936.
To find the number halfway between 21 and 936, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 21 and 936 into our formula, we get:
(21 + 936)/2 = 478.5
Thus, the number halfway between 21 and 936 is 478.5.
To check that our answer is correct, we subtract 21 from 478.5 and subtract 478.5 from 936 and compare the two numbers:
478.5 - 21 = 457.5
936 - 478.5 = 457.5
As you can see, the halfway number is 457.5 higher than 21 and 457.5 lower than 936. Therefore, our halfway between answer of 478.5 above is correct.
