Answer:

#("Ram")/("Aman") = 15/4#

Explanation:

#color(brown)("Using ratio in the FORMAT of a fraction")#

To get the values we need we can look at the units of measurement (identifiers).

Given: #("Ram")/("Rahim") and ("Rahim")/("Aman")#

Target is #("Ram")/("Aman")#

Notice that:

#("Ram")/(cancel("Rahim")) xx (cancel("Rahim"))/("Aman") = ("Ram")/("Aman")# as required

So all we need to do is multiply and simplify

#("Ram")/("Aman")=3/2xx5/2 = 15/4#

Not able to simplify so this is the ration required
