Question

Arrange the following in the descending order question 1 by 5 3 by 7 7 by 10

Answer 1

L.C.M of denominator = 70

now,

1/5 = (1×14)/(5×14) = 14/70

3/7 = (3×10)/(7×10) = 30/70

7/10 = (7×7)/(10×7) = 49/70

now, Arrange the fractions in the descending order

49/70 > 30/70 > 14/70

i.e 7/10 > 3/7 > 1/5 (ans.)
