Answer 1

Answer:

198 is not a perfect square

The LCM of the denominators 20 and 40 is 40 ∴ (15/20) = [(15×2)/ (20×2)] = (30/40) and (35/40) = [(35×1)/ (40×1)] = (35/40) Now, 30 < 35 ⇒ (30/40) < (35/40) Hence, (15/20) < (35/40) ∴ 35/40 is greater. So, between the numbers (15/20) and (35/40), the greater number is (35/40).
