Halfway Between 9 and 70

When you ask "What number is halfway between 9 and 70?" 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=70.

Halfway Between Line

To find the number halfway between 9 and 70, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 70 into our formula, we get:

(9 + 70)/2 = 39.5

Thus, the number halfway between 9 and 70 is 39.5.

To check that our answer is correct, we subtract 9 from 39.5 and subtract 39.5 from 70 and compare the two numbers:

39.5 - 9 = 30.5
70 - 39.5 = 30.5

As you can see, the halfway number is 30.5 higher than 9 and 30.5 lower than 70. Therefore, our halfway between answer of 39.5 above is correct.
