Answer 1

Answer:

10:21 and 30:35:63

Step-by-step explanation:

I) convert into proper fraction

2) l/m = (3/2)/(7/4) = 6/7

similarly m/n= 5/9

3) l/n = (l/m)*(m/n)

=( 6/7)*(5/9) =10/21

4) for l:m:n multiply a number to m and n so that m becomes 7.

m:n = 5:9 = 7:(63/5)

l:m:n= 6:7:(63/5)

you can then multiply all three by 5 if you want

Of it is correct mark me as brainliest
