Halfway Between 11 and 900

When you ask "What number is halfway between 11 and 900?" 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=900.

Halfway Between Line

To find the number halfway between 11 and 900, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 11 and 900 into our formula, we get:

(11 + 900)/2 = 455.5

Thus, the number halfway between 11 and 900 is 455.5.

To check that our answer is correct, we subtract 11 from 455.5 and subtract 455.5 from 900 and compare the two numbers:

455.5 - 11 = 444.5
900 - 455.5 = 444.5

As you can see, the halfway number is 444.5 higher than 11 and 444.5 lower than 900. Therefore, our halfway between answer of 455.5 above is correct.
