Question

Find the sub-triplicate ratio of the following :

`(64  "m"^3)/(729  "n"^3)  : (216  "m"^3)/(27"n"^3)`

Solution

`(64  "m"^3)/(729  "n"^3)  : (216  "m"^3)/(27"n"^3)`

`= ((64  "m"^3)/(729  "n"^3))^(1/3)  : ((216  "m"^3)/(27"n"^3))^(1/3)`

`= (4"m")/(9"n") : (6"m")/(3"n")`

`= (4"m")/(9"n") xx  (6"m")/(3"n")`

`= 2/9`

Sub-triplicate raoo = 2 : 9 

  Is there an error in this question or solution?
