Q 10.     Write the following rational numbers in ascending order:

 

    (ii)         \frac{-1}{3},\frac{2}{9}, \frac{-4}{3}

Answers (1)

Given \frac{-1}{3},\frac{2}{9}, \frac{-4}{3}

LCM of 3,9\ and\ 3 = 9.

Therefore, we have

\frac{1\times3}{3\times3}, \frac{-2\times1}{9\times1}, \frac{-4\times3}{3\times3}

\Rightarrow \frac{3}{9}, \frac{-2}{9}, \frac{-12}{9}

Since \frac{-12}{9}<\frac{-2}{9}<\frac{3}{9}

Hence, the required ascending order is 

\frac{-4}{3}<\frac{-2}{9}<\frac{1}{3}
