Ok, most of these problems require some basic algebra and logical reasoning. They aren't that bad, I promise.
(1)What does 12% mean? How do you express this as a decimal? And once you get the decimal, how can you check to see if those other given fractions are equivalent?
(6)I'll go ahead and set this one up for you.
Do you see the reasoning?
Show me what you've tried on these and post back.
