Hi! @leovaldez

7. anonymous

ur awesome 4 helping me

8. Michele_Laino

thanks!

9. anonymous

sooo

10. anonymous

help?

11. Michele_Laino

I'm pondering...

12. anonymous

kk take ur time

13. anonymous

so done pondering?

14. Michele_Laino

we have these quantities: 6 2/3 = 20/3 cups; 3 1/2= 7/2 cups; 4 3/4 = 19/4 cups, so in total we have: $\frac{{20}}{3} + \frac{7}{2} + \frac{{19}}{4} = ...?$ plese complete that computation

@leovaldez

16. anonymous

yes?

17. anonymous

and how do u simplify it?

18. Michele_Laino

what is the least common multiple of 3, 2 and 4?

19. anonymous

? idk

20. Michele_Laino

hint: $\begin{gathered} 4 = {2^2} \times 1 \hfill \\ 3 = 3 \times 1 \hfill \\ 2 = 2 \times 1 \hfill \\ \end{gathered}$

21. Michele_Laino

you have to pick all common and uncommon factors with the highest exponent

what is the ans im tired i can't think

23. anonymous

i need 2 sleep but not b 4 this work is done i have 2 more

oh im sorry i wasn't thinking see im so tired

$\frac{{20}}{3} + \frac{7}{2} + \frac{{19}}{4} = ...?$ we can't add these fractions until they have a common denominator.

27. anonymous

okkkkk

28. anonymous

i did it

29. anonymous

so i don't get it

30. UsukiDoll

huh?

31. anonymous

i added them but it needs 2 b simplifyed

32. Michele_Laino

33. anonymous

46 over 9

34. UsukiDoll

if you're just adding numerators without finding the least common denominator....I don't believe this.

35. anonymous

wat?

36. UsukiDoll

I know where you got that 9 from 9 = 3+2+4 I said you can't add these fractions because they have different denominators. All of the denominators have to be the same

37. anonymous

so how do i do that?

38. UsukiDoll

find the least common denominator.. or you can just grab all the denominators and multiply them out.

39. UsukiDoll

and then figure out what two numbers are missing for each fraction .

40. anonymous

i know i sound dumb but hey im super tired it's 11:20 where i amggggggggggggggggg lyufhhhhhhhhhhhhkefhyxfyhfgeyx.fylefyglf

41. UsukiDoll

and I don't want to get in trouble in front of a qualified helper.

42. anonymous

sorry im awake im awake!

43. Michele_Laino

@leovaldez please complete these computations: $\begin{gathered} \frac{{20}}{3} = \frac{{20 \times 4}}{{3 \times 4}} = ... \hfill \\ \hfill \\ \frac{7}{2} = \frac{{7 \times 6}}{{2 \times 6}} = ... \hfill \\ \hfill \\ \frac{{19}}{4} = \frac{{19 \times 3}}{{4 \times 3}} = ... \hfill \\ \end{gathered}$

44. anonymous

ok

45. anonymous

there

46. anonymous

did it

47. Michele_Laino

what did you get?
