Question 1.
Observe the products of fractions.
Have you observed the products of any two fractions is always lesser or greater than each of its fraction, write conclusion.
$$\frac{1}{5} \times \frac{2}{3}=\frac{2}{15}$$ (Product of two proper fractions)
Solution:
Product of any two proper fractions is always less than each of its fraction.
i. e., $$\frac{2}{15}<\frac{1}{5} \text { and } \frac{2}{15}<\frac{2}{3}$$

ii) $$\frac{3}{2} \times \frac{5}{4}=\frac{15}{8}$$ (Product of two improper fractions) •
Solution:
The product of any two improper fractions is always greater than each of its fraction.
i.e, $$\frac{3}{2}<\frac{15}{8} \text { and } \frac{5}{4}<\frac{15}{8}$$

iii) $$\frac{2}{3} \times \frac{5}{3}=\frac{10}{9}$$ (Product of proper and improper fractions)
Solution:
The product of a proper fraction and an improper fraction is always greater than its proper fraction and less than its improper fraction.
i.e., $$\frac{2}{3}<\frac{10}{9} \text { and } \frac{5}{3}>\frac{10}{9}$$ (Pg. No. 66)
