1. cail

9 3/5 divided by 2 1/5

2. AbdullahM

First make it into an improper fraction.

3. cail

A. 5 1/10 b. 4 2/5 c. 5 2/11 d. 4 4/11

4. cail

How do I do that ?

5. AbdullahM

$$\bf\large a\frac {b}{c}=\frac {(a\times c)+b}{c}$$

6. cail

Would that be possible if you just gave me the answer ? I suck at this :/

7. MrNood

You will suck at this until you try to do the work yourself

8. cail

I did try

9. MrNood

1/5 means one FIFTH how many 'fifths' are there in 1?

10. cail

It's either b or d right ?

11. AbdullahM

If you choose an answer, make sure to provide work so that way if you make a mistake we can catch it :)

12. MrNood

how many 'fifths' are there in 1 when you answer that then you can work out how many 'fifths' are there in 9?

13. kalynne

make it into an improper fraction.

14. cail

One ?

15. AbdullahM

No...

16. cail

5 ?

17. MrNood

if you divide something into five parts (i.e. into 'fifths') how many oyu got? YES its five so in NINE things - each divided into 5 parts how many parts you got?

18. AbdullahM

Ok, if you have a pie and you cut it up into 5 pieces, how many pieces are there in one pie?

19. cail

5

20. AbdullahM

Then how many total pieces in 9 pies?

21. cail

0.5

22. cail

Wait hold on

23. cail

45 ?

24. AbdullahM

Yes

25. AbdullahM

And so 45 pieces in 9 pies, then how many in 9 3/5 Hint 45 + 3 = ?

26. cail

48

27. AbdullahM

So... 48/5 is the improper fraction for 9 3/5

28. AbdullahM

So now, can you find the improper fraction for 2 1/5

29. cail

And 11/5 for the other one ?

30. AbdullahM

Correct!

31. cail

Okay thanks what do I do next ?

32. AbdullahM

So now the formula for dividing fractions $$\large\bf\frac {a}{b}\div \frac {c}{d} = \frac {a}{b}\times \frac {d}{c} =\frac {ad}{bc}$$

33. cail

I don't understand

34. cail

Is it b ?

35. AbdullahM

Just replace the variables with your numbers :) A can be replaced by 48 B can be replaced by 5 C is replaced by 11 And d is replaced by 5

36. AbdullahM

Don't forget to simplify the fractions before you multiply them.

37. cail

48/5 divided by 11/5 = 48/5 x 5/11 = ?

38. AbdullahM

Correct, amd you can simplify the fractions by dividing the 5 from the numerator and the denominator.

39. AbdullahM

And*

40. cail

I'm on my phone , so I still don't quite understand because when I did this it equally to 4.36

41. cail

Equaled *

42. cail

Actually I just checked right now and it said 0.72

43. AbdullahM

48/5 x 5/11 = 48/11

44. cail

Is it d ?

45. AbdullahM

Make 48/11 into a mixed fraction.

46. AbdullahM

Yes.

47. cail

Okay I did so it is d. Thanks so much !!:)

48. AbdullahM

Anytime :)
