When you ask "What number is halfway between 55 and 128?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=55 and Y=128.
To find the number halfway between 55 and 128, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 55 and 128 into our formula, we get:
(55 + 128)/2 = 91.5
Thus, the number halfway between 55 and 128 is 91.5.
To check that our answer is correct, we subtract 55 from 91.5 and subtract 91.5 from 128 and compare the two numbers:
91.5 - 55 = 36.5
128 - 91.5 = 36.5
As you can see, the halfway number is 36.5 higher than 55 and 36.5 lower than 128. Therefore, our halfway between answer of 91.5 above is correct.
