40 - 28 = 12
1.4286
The GCF is 4.
28/40 = 7/10
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%
