Halfway Between 40 and 647

When you ask "What number is halfway between 40 and 647?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=40 and Y=647.

Halfway Between Line

To find the number halfway between 40 and 647, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 647 into our formula, we get:

(40 + 647)/2 = 343.5

Thus, the number halfway between 40 and 647 is 343.5.

To check that our answer is correct, we subtract 40 from 343.5 and subtract 343.5 from 647 and compare the two numbers:

343.5 - 40 = 303.5
647 - 343.5 = 303.5

As you can see, the halfway number is 303.5 higher than 40 and 303.5 lower than 647. Therefore, our halfway between answer of 343.5 above is correct.
