## Bananas1234 one year ago What is the least common denominator of the fractions? 7/12m^3n, 3/4mn^2

1. xapproachesinfinity

what do you see common there?

2. Bananas1234

the m's?

3. xapproachesinfinity

we have $\frac{7}{12m^3n},~~~ \frac{1}{4mn^2}$

4. xapproachesinfinity

just for abetter look

5. xapproachesinfinity

yah m is common

6. xapproachesinfinity

one of them is m^3 and the other just m so to make it common need to multiply the other by m^2

7. Bananas1234

ok

8. xapproachesinfinity

top and bottom though

9. xapproachesinfinity

what else do you spot is common

10. xapproachesinfinity

keep track of what we are doing ok

11. Bananas1234

the n's?

12. xapproachesinfinity

n is common too right so we need to multiply left one n top and bottom so we get n^2 for both fractions

13. xapproachesinfinity

yes that's right

14. xapproachesinfinity

what about 12 and 4 the common multiple is 12 right (least common multiple)

15. xapproachesinfinity

so we need to multiply the right fraction by 3 top and bottom

16. Bananas1234

yes

17. xapproachesinfinity

are you doing what I'm saying

18. xapproachesinfinity

'cause i asked you to keep track of what we are doing

19. xapproachesinfinity

so now we should have our common denominator ready

20. xapproachesinfinity

can you tell me what it is ?

21. Bananas1234

ok, idk if i did this right 16m^3n^2

22. xapproachesinfinity

hmm 16 should be 12 only

23. xapproachesinfinity

other than that it is good

24. Bananas1234

ok

25. Bananas1234

whats next?

26. xapproachesinfinity

hmm you are asked to find common denominator no? that's all that is the least common deno

27. Bananas1234

Awesome! that was kinda easy! thanks!

28. xapproachesinfinity

for a moment i thought you were not convinced haha

29. Bananas1234

ha ha no i just thought it was more complicated than that :D

30. Bananas1234

Also i checked and the last one that was kinda puzzling was correct.

31. xapproachesinfinity

well it was not apparent :)

32. Bananas1234

yeah

33. xapproachesinfinity

darn the website is slow lol

34. Bananas1234

i ageee

35. xapproachesinfinity

no my reply was to your last question not the previous one

36. xapproachesinfinity

you mean the answer a was the correct

37. Bananas1234

yes

38. xapproachesinfinity

hmm well the way it is set it might be correct but speaking in mathematics it is not

39. Bananas1234

true

40. xapproachesinfinity

are a high school student

41. xapproachesinfinity

you*

42. Bananas1234

no, middle

43. xapproachesinfinity

hmm i see, when you take more math courses you will why we are saying that's wrong

44. xapproachesinfinity

45. Bananas1234

ok i will

46. Bananas1234

Thanks
