Can someone please help me obvert the following categorical propositions?

Hello,
I am teaching myself introductory logic; I bought a textbook. In one of the chapter exercises, I have to obvert a few propositions. Obversion involves changing the quality of a given statement, and then replacing the predicate of the proposition with its term complement. I get that. But I have trouble now obverting these statements:
"No cult leaders are people who fail to brainwash their followers",
"Some college football coaches are people who do not slip money to their players",
and "Some budgetary cutbacks are not actions fair to the poor".

Thank You.

"No cult leaders are people who fail to brainwash their followers",....if I understand what you want
All cult leaders succeed in brainwashing their followers.
Btw, you're supposed to inquire about logic. So, usually reasoning that includes words like "all" suffers from an argument from omniscience fallacy or sweeping generalization depending on how someone forms the argument, how terms are defined, etc...
