When you ask "What number is halfway between 86 and 815?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=86 and Y=815.
To find the number halfway between 86 and 815, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 86 and 815 into our formula, we get:
(86 + 815)/2 = 450.5
Thus, the number halfway between 86 and 815 is 450.5.
To check that our answer is correct, we subtract 86 from 450.5 and subtract 450.5 from 815 and compare the two numbers:
450.5 - 86 = 364.5
815 - 450.5 = 364.5
As you can see, the halfway number is 364.5 higher than 86 and 364.5 lower than 815. Therefore, our halfway between answer of 450.5 above is correct.
