When you ask "What number is halfway between 3 and 64?" 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=64.
To find the number halfway between 3 and 64, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 3 and 64 into our formula, we get:
(3 + 64)/2 = 33.5
Thus, the number halfway between 3 and 64 is 33.5.
To check that our answer is correct, we subtract 3 from 33.5 and subtract 33.5 from 64 and compare the two numbers:
33.5 - 3 = 30.5
64 - 33.5 = 30.5
As you can see, the halfway number is 30.5 higher than 3 and 30.5 lower than 64. Therefore, our halfway between answer of 33.5 above is correct.
