**NCERT Solutions Chapter 08: Comparing Quantities**

In our daily life, there are many occasions when we compare two quantities. Suppose we are comparing heights of Heena and Amir. We find that:

1. Heena is two times taller than Amir.

Or

2. Amir's height is 1/2 of Heena's height.

Consider another example, where 20 marbles are divided between Rita and Amit such that Rita has 12 marbles and Amit has 8 marbles. We say.

1. Rita has 3/2 times the marbles that Amit has.

Or

2. Amit has 2/3 part of what Rita has.
