Advertisements
उत्तर
\[\text{We can write:} \]
\[2 = \frac{2}{1} = \frac{2 \times 5}{1 \times 5} = \frac{10}{5}\]
\[\text{Integers less than}\ 10\ \text{are}\ 0, 1, 2, 3, 4, 5 . . . 9 . \]
\[\text{Hence, five rational numbers less than 2 are} \frac{0}{5}, \frac{1}{5}, \frac{2}{5}, \frac{3}{5} \text{and}\frac{4}{5} . \]
