Answer 1

Answer:

Time taken by Athul to run around the school ground=17 1/3 mintues=52/3

Time taken by Sam to run around the school ground== 12 1/ 5  minutes = 61 /5

                                           LCM of 5,3 = 15

52 5/ 3 5  = 260/ 15                                61 3 /5 3 = 183/ 15

Sam takes less time by 260 /15 - 183 /15  = 77 /15 = 5 2 /15  minutes
