When you ask "What number is halfway between 11 and 777?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=11 and Y=777.
To find the number halfway between 11 and 777, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 11 and 777 into our formula, we get:
(11 + 777)/2 = 394
Thus, the number halfway between 11 and 777 is 394.
To check that our answer is correct, we subtract 11 from 394 and subtract 394 from 777 and compare the two numbers:
394 - 11 = 383
777 - 394 = 383
As you can see, the halfway number is 383 higher than 11 and 383 lower than 777. Therefore, our halfway between answer of 394 above is correct.
