Answer 2

To arrange :  following numbers in the descending order .  

Given data :

Solution :

• To arrange numbers in descending order is to write number from bigger to small .
• Therefore , to arrange given rational numbers in the descending order we need to equalize denominators of all the rational numbers by takin LCM .
• Therefore , LCM = $21$

• Now , multiplying numerators by same numbers as multiplied by denominator to make LCM .
• Therefore, we get , $-3,0, \frac{-11}{7} ,\frac{-21}{3}, -1$$= \frac{-3\times 21}{21} , \frac{0}{21} , \frac{-11\times 3}{21}, \frac{-21\times 7}{21},\frac{-1\times21}{21}$

                                                                       $= \frac{-63}{21} ,0,\frac{-33}{21} \frac{-147}{21} , \frac{-21}{21}$

• Descending order :   $0> \frac{-21}{21} >\frac{-33}{21}>\frac{-63}{21}>\frac{-147}{21}$

Hence , descending order is $0 >-1 >\frac{-11}{7}>-3> \frac{-21}{21}$ .
