What is use of compound ratio?
A:
A compound ratio is basically the product of two or more ratios; thus ab:cd is a ratio compounded of the simple ratios a:c and b:d. (reference).
So the answer to you question is: whenever you would multiply two fractions. For instance, if you want to compute the probability of getting 6 two times out of two on a die, you would do 1/6 * 1/6 = 1/36 which could be seen as a compound ratio.

perhaps, but who can say what the OP meant since he/she did not provide any context.
