Arrange the following in descending order:1/5, 3/7, 7/10

Dear Student

LCM of 5, 7, 10 = 70
Now, let us change each of the given fraction into an equivalent fraction having 70 as the denominator.
[(1/5) × (14/14)] = (14/70) [(3/7) × (10/10)]
= (30/70) [(7/10) × (7/7)]
= (49/70)
Clearly,
(49/70) > (30/70) > (14/70)
Hence,
(7/10) > (3/7) > (1/5)
Hence, the given fractions in descending order are (7/10), (3/7), (1/5)

Thanks
