Since the quiz/test (or whatever it may be) is out of '40' we know that 40 out of 40 is 100%, or the full marks.
Now, since we know that, we can divide 28 by 40.
28/40 = 0.7
After, we take this number and multiply it by 100 to make it equal to the percentage..
0.7 x 100 = 70
So, 28 out of 40 is equal to 70%
