Halfway Between 9 and 140

When you ask "What number is halfway between 9 and 140?" 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=140.

Halfway Between Line

To find the number halfway between 9 and 140, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 140 into our formula, we get:

(9 + 140)/2 = 74.5

Thus, the number halfway between 9 and 140 is 74.5.

To check that our answer is correct, we subtract 9 from 74.5 and subtract 74.5 from 140 and compare the two numbers:

74.5 - 9 = 65.5
140 - 74.5 = 65.5

As you can see, the halfway number is 65.5 higher than 9 and 65.5 lower than 140. Therefore, our halfway between answer of 74.5 above is correct.
