Whats the question?

2. anonymous

$-\frac{ 9 }{ 6 }+(-\frac{ 3 }{ 5 })$

3. anonymous

Oi o-o

4. anonymous

Dunno

5. anonymous

If you are adding a negative fraction, you are just subtracting them both.

6. anonymous

You need to make them have the same base though.

7. anonymous

lol i got to put it in simplest form

8. anonymous

i got -12/5 and in mixed form its -2 2/5

9. anonymous

What did you do for that? Did you make them both have the base of 30 and then simplify?

10. anonymous

no but the denominate is 5 so it stays soo

11. anonymous

then just add

12. anonymous

No that doesn't work.

13. anonymous

They need to have a common demoninator.

14. anonymous

-9+-3=12

15. anonymous

it does its 5

16. anonymous

No the fractions have two different denominators. 5 and 6 aren't the same so you need to make a common denominator.

17. anonymous

damn i typed it wro ng on a calculator

18. anonymous

You need to multiply the first fraction by 5 and the second by 6 to get the demoninator of 30.

19. anonymous
