Answer 1

Answer:

(17:21) ,( 11:14) , (5:7)

Answer 2

Step by step explanation :

We can write 5 : 7 in fraction 5/7 , 11 : 14 = 11/14 , 17 : 21 = 17/21

Now find the LCM of denominators 7 , 14 , 21

5 : 7 = 30 : 42 = 30/42

11 : 14 = 33 : 42 = 33/42

17 : 21 = 34 : 42 = 34/42

Descending order :

34/42 , 33/42 , 30/42

= 17 : 21 , 11 : 14 , 5 : 7

OR

Remember that Fraction with greater denominator is always greater....

Here denominator 21 is greater than 14 and 7

Therefore 17 : 21 , 11 : 14 , 5 : 7
