Answer 5

I will give medals

Answer 6

umm... I can try... but I'm kinda going cross-eyed >,<
could you try pressing the "Equation" button or the "Draw" button to make it more clear? Thanks :)

Answer 8

okay cool, thanks :)

now you know how m over m = 1 and therefore cancels out when multiplying?

Answer 9

yes

Answer 10

then
\[\frac{ 4m ^{3} }{ 3m ^{2}n } * \frac{ 9n ^{2} }{ 30m ^{2}n ^{2} } \rightarrow \frac{ 4m ^{2}9n ^{2} }{ 3m ^{2}n30m ^{2}n ^{2} }\]

Answer 11

and\[\frac{ 4m ^{2}9n ^{2} }{ 3m ^{2}n30m ^{2}n ^{2} } \rightarrow \frac{ 4*9*m*m*n*n }{ 3*30*m*m*m*m*n*n*n }\]

Answer 12

m*m*m can be canceled out from the top and bottom
n*n can be canceled out from the top and bottom as well
then you'll be left with:
\[\frac{ 36 }{ 90mn }\]then 36 over 90 can be simplified :)

Answer 13

the choices are

1) 2n
--
3m

2) 2m
--
5n

3) 2
--
3mn

4) 2
--
5mn

Answer 14

@jigglypuff314

Answer 15

36 and 90 can both be divided by 18
so 36 over 90 would equal 2 over 5
and mn is in the denominator :)

Answer 16

thank you so much!!!
