Answer 7

We want to be able to add and subtract the fractions, but we can't because the denominators are all different. So we want to come up with one that we can translate all the fractions with. The denominators are 3,6=(2)(3), and 9=(3)(3). So let's try(2)(3)(3)=18. So let's use that\[=\frac{-7}{3} - \frac56 + \frac49=\frac{-42-15+8}{18}=?\]

Answer 8

-49/18
