(a) 5/9 equal to 4/5
5/9 and 4/5
= 5×5/9×5 =25/45 and 4×9/5×9 = 36/45 [ L.C.M. of 9 and 5 is 45]
Since, 25/45≠36/45
Therefore, 5/9≠4/5
(b) 9/16 equal to 5/9
= 9×9/16×9 = 81/144 and 5×16/9×16=80/144 [ L.C.M. of 16 and 9 is 144]
Since,81/144≠80/144
Therefore,9/16≠5/9
(c) 4/5 equal to 16/20
= 4×20/5×20=80/100 and 16×5/20×5=80/100 [ L.C.M. of 5 and 20 is 100]
Since,80/100≠80/100
Therefore,4/5≠16/20
(D) 1/15 equal to 4/30
= 1×2/15×2 = 2/30 and 4×1/30/1 = 4/30 [ L.C.M. of 15 and 30 is 30]
Since,4/30 = 4/30
Therefore,1/15≠4/30
