Best ResponseYou've already chosen the best response.0If they all have the same denominator you may combine them appropriately with their sign. In the case above they are common, both being 15 you can just add getting 12/15 You can divide top and bottom without changing the value getting 5/5 which is equivalent to 12/15 or is the reduced version.

Best ResponseYou've already chosen the best response.0You shouldn't get 5/5 when you divide by 3 how about 4/5 lol

Best ResponseYou've already chosen the best response.01/3 + 1/6 Needs a common denominator. It makes sense to get one that is small as possible to keep the problem simple. I am looking for a number that is as small as possible that has a factor 6 and 3. This one is easy as the 6 will contain the 6 and it also contains the 3 (3 x 2 = 6)

Best ResponseYou've already chosen the best response.0Yes the 9/11 was correct. To the problem at hand, what do you need to multply the denominator 3 to get 6? I'll be back later

Best ResponseYou've already chosen the best response.0If you reasoned it to be 2 you are correct. Multiply both top and bottom by 2 getting 2/6 since the second fraction already has 6 we can play we multiplied top and bottom by 1. 2/6 +1/6 = 3/6 we can reduce this by dividing top and bottom by 3 getting 1/2
