When you ask "What number is halfway between 31 and 644?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=31 and Y=644.
To find the number halfway between 31 and 644, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 31 and 644 into our formula, we get:
(31 + 644)/2 = 337.5
Thus, the number halfway between 31 and 644 is 337.5.
To check that our answer is correct, we subtract 31 from 337.5 and subtract 337.5 from 644 and compare the two numbers:
337.5 - 31 = 306.5
644 - 337.5 = 306.5
As you can see, the halfway number is 306.5 higher than 31 and 306.5 lower than 644. Therefore, our halfway between answer of 337.5 above is correct.
