When you ask "What number is halfway between 30 and 73?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=30 and Y=73.
To find the number halfway between 30 and 73, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 30 and 73 into our formula, we get:
(30 + 73)/2 = 51.5
Thus, the number halfway between 30 and 73 is 51.5.
To check that our answer is correct, we subtract 30 from 51.5 and subtract 51.5 from 73 and compare the two numbers:
51.5 - 30 = 21.5
73 - 51.5 = 21.5
As you can see, the halfway number is 21.5 higher than 30 and 21.5 lower than 73. Therefore, our halfway between answer of 51.5 above is correct.
