Question

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

Answer 1

what do you see common there?

Answer 2

the m's?

Answer 3

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

Answer 4

just for abetter look

Answer 5

yah m is common

Answer 6

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

Answer 7

ok

Answer 8

top and bottom though

Answer 9

what else do you spot is common

Answer 10

keep track of what we are doing ok

Answer 11

the n's?

Answer 12

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

Answer 13

yes that's right

Answer 14

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

Answer 15

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

Answer 16

yes

Answer 17

are you doing what I'm saying

Answer 18

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

Answer 19

so now we should have our common denominator ready

Answer 20

can you tell me what it is ?

Answer 21

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

Answer 22

hmm 16 should be 12 only

Answer 23

other than that it is good

Answer 24

ok

Answer 25

whats next?

Answer 26

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