Arrange 6 12 , 5 12 , 2 3 , 3 8 in ascending order.

Given, 6 12 , 5 12 , 2 3 , 3 8 As we can see that denominators of all fractions are different First we find the L.C.M. of the denominators of the fractions to make the denominators same. L.C.M of 12 , 12 , 3 and 8 is 24 Now, = 6 × 2 12 × 2 , 5 × 2 12 × 2 , 2 × 8 3 × 8 , 3 × 3 8 × 3 = 12 24 , 10 24 , 16 24 , 9 24 Comparing numerators, we find that 9 24 < 10 24 < 12 24 < 16 24 Thus, the ascending order of given fraction is 3 8 < 5 12 < 6 12 < 2 3

Arrange 3 7 , 9 35 , 11 14 , 13 28 in descending order.

Given, 3 7 , 9 35 , 11 14 , 13 28 As we can see that denominators of all fractions are different First we find the L.C.M. of the denominators of the fractions to make the denominators same. L.C.M of 7 , 35 , 14 and 28 is 140 Now, = 3 × 20 7 × 20 , 9 × 4 35 × 4 , 11 × 10 14 × 10 , 13 × 5 28 × 5 = 60 140 , 36 140 , 110 140 , 65 140 Comparing numerators, we find that 110 140 > 65 140 > 60 140 > 36 140 Thus, the ascending order of given fraction is 11 14 > 13 28 > 3 7 > 9 35

If the cost of a notebook is ₹ 12 3 4 , how many notebooks can be purchased for ₹ 191 1 4 ?

Given, Cost of one notebook is ₹ 12 3 4 Number of books can be purchased for ₹ 191 1 4 is = Price to purchase number of books ÷ cost of one book. 191 1 4 ÷ 12 3 4 = 765 4 ÷ 51 4 = 765 4 × 4 51 = 15 Number of books can be purchase is 15

By what number should be 4 5 6 multiplied to get 9 1 6 ?

Let the number be x . So, x × 4 5 6 = 9 1 6 ⇒ x × 29 6 = 55 6 ⇒ x = 55 6 ÷ 29 6 ⇒ x = 55 6 × 6 29 ⇒ x = 55 29 = 1 26 29 Thus, the number is 1 26 29

By what fraction should 5 3 7 be divided to get 4 7 ?

Let the fraction be x . So, 5 3 7 ÷ x = 4 7 ⇒ 5 3 7 ÷ 4 7 = x ⇒ 38 7 × 7 4 = x ⇒ 19 2 = 9 1 2 = x Thus, the fraction is 9 1 2
