Halfway Between 43 and 644

When you ask "What number is halfway between 43 and 644?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=43 and Y=644.

Halfway Between Line

To find the number halfway between 43 and 644, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 43 and 644 into our formula, we get:

(43 + 644)/2 = 343.5

Thus, the number halfway between 43 and 644 is 343.5.

To check that our answer is correct, we subtract 43 from 343.5 and subtract 343.5 from 644 and compare the two numbers:

343.5 - 43 = 300.5
644 - 343.5 = 300.5

As you can see, the halfway number is 300.5 higher than 43 and 300.5 lower than 644. Therefore, our halfway between answer of 343.5 above is correct.
