just for abetter look
xapproachesinfinity
  • xapproachesinfinity
yah m is common
xapproachesinfinity
  • 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
Bananas1234
  • Bananas1234
ok
xapproachesinfinity
  • xapproachesinfinity
top and bottom though
xapproachesinfinity
  • xapproachesinfinity
what else do you spot is common
xapproachesinfinity
  • xapproachesinfinity
keep track of what we are doing ok
Bananas1234
  • Bananas1234
the n's?
xapproachesinfinity
  • 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
xapproachesinfinity
  • xapproachesinfinity
yes that's right
xapproachesinfinity
  • xapproachesinfinity
what about 12 and 4 the common multiple is 12 right (least common multiple)
xapproachesinfinity
  • xapproachesinfinity
so we need to multiply the right fraction by 3 top and bottom
Bananas1234
  • Bananas1234
yes
xapproachesinfinity
  • xapproachesinfinity
are you doing what I'm saying
xapproachesinfinity
  • xapproachesinfinity
'cause i asked you to keep track of what we are doing
xapproachesinfinity
  • xapproachesinfinity
so now we should have our common denominator ready
xapproachesinfinity
  • xapproachesinfinity
can you tell me what it is ?
Bananas1234
  • Bananas1234
ok, idk if i did this right 16m^3n^2
xapproachesinfinity
  • xapproachesinfinity
hmm 16 should be 12 only
xapproachesinfinity
  • xapproachesinfinity
other than that it is good
Bananas1234
  • Bananas1234
ok
Bananas1234
  • Bananas1234
whats next?
xapproachesinfinity
  • xapproachesinfinity
hmm you are asked to find common denominator no? that's all that is the least common deno
Bananas1234
  • Bananas1234
Awesome! that was kinda easy! thanks!
xapproachesinfinity
  • xapproachesinfinity
for a moment i thought you were not convinced haha
Bananas1234
  • Bananas1234
ha ha no i just thought it was more complicated than that :D
Bananas1234
  • Bananas1234
Also i checked and the last one that was kinda puzzling was correct.
xapproachesinfinity
  • xapproachesinfinity
well it was not apparent :)
Bananas1234
  • Bananas1234
yeah
xapproachesinfinity
  • xapproachesinfinity
darn the website is slow lol
Bananas1234
  • Bananas1234
i ageee
xapproachesinfinity
  • xapproachesinfinity
no my reply was to your last question not the previous one
xapproachesinfinity
  • xapproachesinfinity
you mean the answer a was the correct
Bananas1234
  • Bananas1234
yes
xapproachesinfinity
  • xapproachesinfinity
hmm well the way it is set it might be correct but speaking in mathematics it is not
Bananas1234
  • Bananas1234
true
xapproachesinfinity
  • xapproachesinfinity
are a high school student
xapproachesinfinity
  • xapproachesinfinity
you*
Bananas1234
  • Bananas1234
no, middle
xapproachesinfinity
  • xapproachesinfinity
hmm i see, when you take more math courses you will why we are saying that's wrong
xapproachesinfinity
  • xapproachesinfinity
but just tell your teacher!
Bananas1234
  • Bananas1234
ok i will
Bananas1234
  • Bananas1234
Thanks
