Arrange the following rational numbers in descending order
$-\frac{3}{10} ,\frac{-7}{-5}, \frac{9}{-15}, 1\frac{8}{30}$.
Given:
The numbers given are
$-\frac{3}{10} ,\frac{-7}{-5}, \frac{9}{-15}, 1\frac{8}{30}$.
To do: Arrange the following rational numbers in descending order
SOlution:
=$-\frac{3}{10} ,\frac{-7}{-5}, \frac{9}{-15}, 1\frac{8}{30}$.
=$-\frac{3}{10} ,\frac{7}{5}, \frac{9}{-15}, \frac{38}{30}$.
=LCM of 10, 5,15,30 is 30
=$\frac{3x3}{30} ,\frac{7\times6}{30},\frac{9\times(-2)}{30},\frac{38}{30}$
=$\frac{9}{30} ,\frac{42}{30},\frac{-18}{30},\frac{38}{30}$
The descending order is
$ \frac{38}{30}, \frac{42}{30},\frac{9}{30},\frac{-18}{30}$
