Heya

Duplicate ratio of a:b is a²:b²
Triplicate ratio of a:b is a³:b³

Duplicate ratio of 3:4 is 3²:4² = 9:16

Triplicate ratio of 2:3 is 2³:3³ = 8:27

Ratios we have now are 4:9 , 9:16, 8:27, 9:7

Compounded ratio = (4×9×8×9):(9×16×27×7)

= 2592:27216

=162 :1701

Hope it helps! ^_^

SOLUTION:--
____________________________________

●duplicate ratio= 3:4

3^2/4^2 = 9/16. 

●triplicate ratio =2:3
2^3/3^3 = 8/27.

SIMILARLY,

4 ratios= 4:9, 9:16, 8:27, 9:7.

●calculate the ratio compound

= (4 x 9 x 8 x 9)/(9 x 16 x 27 x 7)

= 2,592/27,216

= [ 2/21.]ans
