Halfway Between 45 and 80

When you ask "What number is halfway between 45 and 80?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=45 and Y=80.

Halfway Between Line

To find the number halfway between 45 and 80, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 80 into our formula, we get:

(45 + 80)/2 = 62.5

Thus, the number halfway between 45 and 80 is 62.5.

To check that our answer is correct, we subtract 45 from 62.5 and subtract 62.5 from 80 and compare the two numbers:

62.5 - 45 = 17.5
80 - 62.5 = 17.5

As you can see, the halfway number is 17.5 higher than 45 and 17.5 lower than 80. Therefore, our halfway between answer of 62.5 above is correct.
