. Arrange the following fractions 5/6, 7/10, 11/20 in descending order.
First we find the L.C.M. of the denominators of the fractions to make the denominators same.
L.C.M. of 6, 10 and 20
L.C.M. of 6, 10 and 20 = 2 × 5 × 3 × 1 × 2 = 60
5/6 = 5 × 10/6 × 10 = 50/60 (because 60 ÷ 6 = 10)
7/10 = 7 × 6/10 × 6 = 42/60 (because 60 ÷ 10 = 6)
11/20 = 11 × 3/20 × 3 = 33/60 (because 60 ÷ 20 = 3)
