When you ask "What number is halfway between 69 and 78?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=69 and Y=78.
To find the number halfway between 69 and 78, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 69 and 78 into our formula, we get:
(69 + 78)/2 = 73.5
Thus, the number halfway between 69 and 78 is 73.5.
To check that our answer is correct, we subtract 69 from 73.5 and subtract 73.5 from 78 and compare the two numbers:
73.5 - 69 = 4.5
78 - 73.5 = 4.5
As you can see, the halfway number is 4.5 higher than 69 and 4.5 lower than 78. Therefore, our halfway between answer of 73.5 above is correct.
