When you ask "What number is halfway between 87 and 440?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=87 and Y=440.
To find the number halfway between 87 and 440, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 87 and 440 into our formula, we get:
(87 + 440)/2 = 263.5
Thus, the number halfway between 87 and 440 is 263.5.
To check that our answer is correct, we subtract 87 from 263.5 and subtract 263.5 from 440 and compare the two numbers:
263.5 - 87 = 176.5
440 - 263.5 = 176.5
As you can see, the halfway number is 176.5 higher than 87 and 176.5 lower than 440. Therefore, our halfway between answer of 263.5 above is correct.
