When you ask "What number is halfway between 64 and 639?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=64 and Y=639.
To find the number halfway between 64 and 639, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 64 and 639 into our formula, we get:
(64 + 639)/2 = 351.5
Thus, the number halfway between 64 and 639 is 351.5.
To check that our answer is correct, we subtract 64 from 351.5 and subtract 351.5 from 639 and compare the two numbers:
351.5 - 64 = 287.5
639 - 351.5 = 287.5
As you can see, the halfway number is 287.5 higher than 64 and 287.5 lower than 639. Therefore, our halfway between answer of 351.5 above is correct.
