This is a basic question from ML aggarwal book of class 10th, chapter 7, ratio and proportion., ICSE board
In this particular type of question, we have been given a ratio in the form of the a:b and we have to find the triplicate ratio of it.
Question no 4, chapter 7
Solution:
(i) 3: 4
We know that
Triplicate ratio of 3: 4 = 33: 43 = 27: 64
(ii) ½: 1/3
We know that
Triplicate ratio of ½: 1/3 = (1/2)3: (1/3)3 = 1/8: 1/27 = 27: 8
(iii) 13: 23
We know that
Triplicate ratio of 13: 23 = (13)3: (23)3 = 13: 83 = 1: 512
