Halfway Between 80 and 669

When you ask "What number is halfway between 80 and 669?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=80 and Y=669.

Halfway Between Line

To find the number halfway between 80 and 669, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 669 into our formula, we get:

(80 + 669)/2 = 374.5

Thus, the number halfway between 80 and 669 is 374.5.

To check that our answer is correct, we subtract 80 from 374.5 and subtract 374.5 from 669 and compare the two numbers:

374.5 - 80 = 294.5
669 - 374.5 = 294.5

As you can see, the halfway number is 294.5 higher than 80 and 294.5 lower than 669. Therefore, our halfway between answer of 374.5 above is correct.
