Ila read 25 pages of a book containing 100 pages. Lalita read 2 5 of the same book. Who read less?

Given, Lalita read 2 5 t h part of book. Ila reads 25 pages out of 100 pages, Fraction of the pages Ila reads = 25 100 = 25 ÷ 5 100 ÷ 5 = 5 ÷ 5 20 ÷ 5 = 1 4 So, Ila read 1 4 th part of the book. We have to find out who read less, Since the denominators are different, we need to make the denominators same by finding their common denominator. L.C.M of 4 , 5 = 2 × 2 × 5 = 20 Now, 1 4 = 1 × 5 4 × 5 = 5 20 2 5 = 2 × 4 5 × 4 = 8 20 Since 5 20 < 8 20 Therefore, 1 4 < 2 5 Hence, Ila read less than Lalita.

Rafiq exercised for 3 6 of an hour, while Rohit exercised for 3 4 of an hour. Who exercised for a longer time?

Given, Rafiq exercised 3 6 of an hour. Rohit exercised 3 4 of an hour. Now, we have to compare these fractions to see who exercised for a longer time. So, since the denominators are different, we need to make the denominators same by finding their common denominator. 2 6 , 4 2 3 , 2 3 3 , 1 1 , 1 L.C.M of 6 , 4 = 2 × 2 × 3 = 12 Now, 3 6 = 3 × 2 6 × 2 = 6 12 3 4 = 3 × 3 4 × 3 = 9 12 Since 6 12 < 9 12 ⟹ 3 6 < 3 4 Therefore, Rohit exercised for a longer time than Rafiq.
