When you ask "What number is halfway between 57 and 420?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=57 and Y=420.
To find the number halfway between 57 and 420, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 57 and 420 into our formula, we get:
(57 + 420)/2 = 238.5
Thus, the number halfway between 57 and 420 is 238.5.
To check that our answer is correct, we subtract 57 from 238.5 and subtract 238.5 from 420 and compare the two numbers:
238.5 - 57 = 181.5
420 - 238.5 = 181.5
As you can see, the halfway number is 181.5 higher than 57 and 181.5 lower than 420. Therefore, our halfway between answer of 238.5 above is correct.
