He mate:

Given :

=> l : m = 3/2 : 7/4

then,

l : m = 6 : 7

l , m = 6, 7

=> m : n = 7/3 : 21/5

then,

m : n = 5 : 9

m, n = 5, 9

=> l : n = 6 : 9 = 2 : 3
________________

And,

let,

l : m1 = 6 : 7

m2 : n =5 : 9

Then

l : m : n = lm2 : m1m2 : m1n

l : m : n = 6 × 7 : 7 × 5 : 5 × 9

l : m : n = 42 : 35 : 45
