studied comparison of fractions, equivalent fractions, representation of fractions on the

number line and ordering of fractions.

Our study of decimals included, their comparison, their representation on the number

line and their addition and subtraction.

We shall now learn multiplication and division of fractions as well as of decimals.**2.2 HOW WELL HAVE YOU LEARNT ABOUT FRACTIONS?**

- multiplied.
- (b) The product of a proper and an improper fraction is less than the improper
- fraction and greater than the proper fraction.
