The first two are correct.
there has to be a misprint in the third, since according to your question you are appr. doing 1/5 * 5 which is 1

The second and third are wrong. There is no correct answer for the second.
2/3 of 3/4 is 1/2

I believe the problem in the third one is:
2 1/5 * 4 5/6
C is not the correct answer.
