Answer 2

here's ur answer
(a) the largest rational no among the given nos should be +ve
so it must be 4/7 or 5/9
multiplying 4/7 by 9/9,we get
36/63
multiplying 5/9 by 7/7, we get
35/63
here 36/63 > 35/63
so 4/7 > 5/9
hence largest rational no among the given nos is 4/7
||ly the smallest rational no should be -ve
multiplying -4/7 by 15/15, we get
-60/105
multiplying -7/15 by 7/7, we get
-49/105
here -49/105 > -60/105
so -7/15 > -4/7
hence smallest rational no among the given nos is -4/7
