When you ask "What number is halfway between 30 and 643?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=30 and Y=643.
To find the number halfway between 30 and 643, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 30 and 643 into our formula, we get:
(30 + 643)/2 = 336.5
Thus, the number halfway between 30 and 643 is 336.5.
To check that our answer is correct, we subtract 30 from 336.5 and subtract 336.5 from 643 and compare the two numbers:
336.5 - 30 = 306.5
643 - 336.5 = 306.5
As you can see, the halfway number is 306.5 higher than 30 and 306.5 lower than 643. Therefore, our halfway between answer of 336.5 above is correct.
