You already have the answer. It is "One type of proof is a two-column proof. It contains statements and reasons in columns. Another type is a paragraph proof, in which statements and reasons are written in words. A third type is a flowchart proof, which uses a diagram to show the steps of a proof." which looks correct to me.
A) 2 2/9
The answer would of course be positive because two negatives make a positive.
It would only be 6 4/9 if you added when here it states the obvious for you to subtract.
Hope this helped PLEASE MARK BRAINLIEST!!
