I've spent hours on this and I keep getting mixed answers. I need to know the rules for multipling, dividing, adding, subtracting equations involving fractions. I google search but the information is not organized, I get sources telling me to find a common denominator, to multiply by the inverse, to just combine the fractions and all these stuff. If someone can please guide me its pretty elementary maths but it would help alot here are some of the questions I should be able to do:
I used to be able to do these but I just forgot since it's been a while. If I can do these, I can be able to do anything. If you are going to show please explain using words the steps you did it would help alot thanks. Relevant khanacademy links would be appreciated (could not find them there).
