3/4
8016 is an integer, and there is no sensible way to represent it as a fraction.
8/40 = 1/5
No but as a decimal 9/20 is equivalent to 0.45
No. 7 is a prime number which means it is only divisible by one and itself. 40 is not divisible by seven. (In other, shorter words, 7 and 40 have no common factor.)

8016 is an integer, and there is no sensible way to represent it as a fraction.
72/100 = 18/25
8/40 = 1/5
2/3 cannot be simplified further.
0.05 = 5/100 = 1/20
No but as a decimal 9/20 is equivalent to 0.45
As a whole number with a fraction, that's three and six tenths (3 and 6/10ths). This can be expressed at 3.6
As a fraction, it can't be reduced to lower terms. Butit would look a lot better if it were written as 11/48 .
3/76 is in simplest form. 3 is a prime number that will not go into 76, so there are no factors in common in order to simplify the fraction.
-0.8 is, itself, a fraction. It is a fraction in decimal form rather than in the form of a ratio. However, that does not stop it being a fraction, and it is in its simplest form since there are no trailing 0s or recurring 9s. Its equivalent, in rational form, is -8/10 which can be simplified to -4/5.
