When you ask "What number is halfway between 87 and 510?" 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=510.
To find the number halfway between 87 and 510, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 87 and 510 into our formula, we get:
(87 + 510)/2 = 298.5
Thus, the number halfway between 87 and 510 is 298.5.
To check that our answer is correct, we subtract 87 from 298.5 and subtract 298.5 from 510 and compare the two numbers:
298.5 - 87 = 211.5
510 - 298.5 = 211.5
As you can see, the halfway number is 211.5 higher than 87 and 211.5 lower than 510. Therefore, our halfway between answer of 298.5 above is correct.
