First we find the L.C.M. of the denominators of the fractions to make the denominators same.

L.C.M. = 3 × 2 × 3 × 1 = 18

Now to make the fraction as like fractions divide the L.C.M. by the denominator of fractions, then multiply both the numerator and denominator of fraction with the number get after dividing L.C.M.

As in fraction  denominator is 6.

Divide 18 ÷ 6 = 3

Now, multiply both numerator and denominator by 3 = 5 × × 3 =

(because 18 ÷ 9 = 2)

(because 18 ÷ 3 = 6)

Now, we compare the like fractions

Comparing numerators, we find that 16 > 15 > 12

The ascending order of the fractions is
