When you ask "What number is halfway between 9 and 557?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=9 and Y=557.
To find the number halfway between 9 and 557, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 9 and 557 into our formula, we get:
(9 + 557)/2 = 283
Thus, the number halfway between 9 and 557 is 283.
To check that our answer is correct, we subtract 9 from 283 and subtract 283 from 557 and compare the two numbers:
283 - 9 = 274
557 - 283 = 274
As you can see, the halfway number is 274 higher than 9 and 274 lower than 557. Therefore, our halfway between answer of 283 above is correct.
