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 = 3

^{3}: 4^{3}= 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) 1

^{3}: 2^{3}We know that

Triplicate ratio of 1

^{3}: 2^{3}= (1^{3})^{3}: (2^{3})^{3}= 1^{3}: 8^{3}= 1: 512
