   Show answer

   Answer: (3) 1666

   సమాధానం: (3) 1666

   The numbers are 21/10 and 51/35. LCM of fractions = LCM(21, 51)/HCF(10, 35) = 357/5 and HCF = HCF(21, 51)/LCM(10, 35) = 3/70, so x/y = (357/5) × (70/3) = 1666.

   సంఖ్యలు 21/10 మరియు 51/35. భిన్నాల క.సా.గు. = LCM(21, 51)/HCF(10, 35) = 357/5 మరియు గ.సా.భా. = HCF(21, 51)/LCM(10, 35) = 3/70, కాబట్టి x/y = (357/5) × (70/3) = 1666.
