Halfway Between 9 and 679

When you ask "What number is halfway between 9 and 679?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=9 and Y=679.

Halfway Between Line

To find the number halfway between 9 and 679, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 679 into our formula, we get:

(9 + 679)/2 = 344

Thus, the number halfway between 9 and 679 is 344.

To check that our answer is correct, we subtract 9 from 344 and subtract 344 from 679 and compare the two numbers:

344 - 9 = 335
679 - 344 = 335

As you can see, the halfway number is 335 higher than 9 and 335 lower than 679. Therefore, our halfway between answer of 344 above is correct.
