The duplicate ratio of 3:4 is 3^2/4^2 = 9/16.
The triplicate ratio of 2:3 is 2^3/3^3 = 8/27.
Now we have 4 ratios: 4:9, 9:16, 8:27 and 9:7.
We have to calculate the ratio compounded of all these ratios.
That will be (4 x 9 x 8 x 9)/(9 x 16 x 27 x 7) = 2/21.
The triplicate ratio of 2:3 is 2^3/3^3 = 8/27.
Now we have 4 ratios: 4:9, 9:16, 8:27 and 9:7.
We have to calculate the ratio compounded of all these ratios.
That will be (4 x 9 x 8 x 9)/(9 x 16 x 27 x 7) = 2/21.
