Question

Arrange the fractions in descending order:
3/5, 7/8, 6/9, 4/7

Answer 1

Answer:

In descending order that would be

7/8>6/9>3/5>4/7

Answer 2

To arrange :  following numbers in the descending order .  

Given data : $\frac{3}{5}, \frac{7}{8}, \frac{6}{9}, \frac{4}{7}$

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 = $2520$

• Now , multiplying numerators by same numbers as multiplied by denominator to make LCM .

• Therefore, we get , $\frac{3\times504}{2520},\frac{7\times 315}{2520},\frac{6\times280}{2520}, \frac{4\times 360}{2520}$  

                                       $= \frac{1512}{2520} , \frac{2205}{2520} , \frac{1680}{2520}, \frac{1440}{2520}$

         Hence , Descending order is :  $\frac{2205}{2520} >\frac{1680}{2520} >\frac{1512}{2520} >\frac{1440}{2520}$ or  

                                                               $\frac{7}{8} > \frac{6}{9} > \frac{3}{5} > \frac{4}{7}$
