Answer 3

First, convert the fractions into improper fractions.

Do you know how to do that?

Answer 4

only a lil. my mind went blank after the week i learned it.

Answer 5

\(\Large a\frac{b}{c} = \frac{(a~\cdot~ c)~ + ~b}{c}\)

Answer 6

oh okay

Answer 7

i got

- 17/5
and
46/5

Answer 8

Check the second improper fraction again

Answer 9

41/5

Answer 10

correct

Answer 11

We now have:

\(\Large- \frac{17}{5} + b = \frac{41}{5}\)

Rearrange the terms

\(\Large b - \frac{17}{5}= \frac{41}{5}\)

Add 17/5 on both sides

\(\Large b = \frac{41}{5}+\frac{17}{5}\)

Can you simplify that more? :)

Answer 12

I would have to say yes. Even though i am not sure i would have to say yes

Answer 13

Then simplify it :P

Answer 14

Hint: \(\Large \frac{a}{c} + \frac{b}{c} = \frac{a~+~b}{c}\)
