make them into an improper fraction first

4. anonymous

so like I did kinda?

5. anonymous

no. make them improper fractions by taking away the whole number. So the first mixed number would turn into 46/3 and the second one would turn into 19/2

6. anonymous

Ok hod on

8. anonymous

yeah! :) Do you know how did i converted them from mixed to improper though? :o

9. anonymous

*convert

11. anonymous

Yes I actually did that myself I didn't see your answers til' I finished :)

12. anonymous

exactly! now just subtract the numerators and turn it back into a mixed number :)

13. anonymous

14. anonymous

Right?

15. anonymous

okay, now turn it back to a mixed number if it's asked :)

16. anonymous

No it's not asked. So I would leave it like that?

17. anonymous

6 35/6

18. anonymous

ummm, i guess you should turn it back into a mixed number since the problem was given to you as a mixed number

19. anonymous

20. anonymous

oh thanks

21. anonymous

your final answer would be $5 \frac{ 5 }{ 6}$

22. anonymous

or, just ignore the fraction first, add the whole numbers then add the fractions.

23. anonymous

um okk........

24. anonymous

converting them to improper form is unnecessary and tedious. just do (15-9) + [(1/3) - (1/2)]

25. anonymous

Algebraically, you can say: let a = first constant let b = first fraction let c = second constant let d = second fraction (a-c) + (b-d)

26. anonymous

ok but wouldn't you have to make 1/3 and 1/2 make the denominators 6
