When you ask "What number is halfway between 3 and 640?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=3 and Y=640.
To find the number halfway between 3 and 640, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 3 and 640 into our formula, we get:
(3 + 640)/2 = 321.5
Thus, the number halfway between 3 and 640 is 321.5.
To check that our answer is correct, we subtract 3 from 321.5 and subtract 321.5 from 640 and compare the two numbers:
321.5 - 3 = 318.5
640 - 321.5 = 318.5
As you can see, the halfway number is 318.5 higher than 3 and 318.5 lower than 640. Therefore, our halfway between answer of 321.5 above is correct.
