Question

Sandeeep takes 4 1/5 miutes to walk across the school ground.Ramesh takes 7/3 munutes to do the same.Who takes more time and by what fraction?(The result should be sandeep by 1 13/15 minutes)​

Answer 1

Answer:

Step-by-step explanation:

Sandeep took = 4 1/5 min = 21 / 5 min

Ramesh took = 7 / 3 min

Sandeep time - Ramesh time = 21/5 - 7/3

                taking LCM of denominators 5x3 = 15

                                              = (21x3 / 15) - (7x5 / 15)

                                              = 63 / 15 - 35 / 15

                                              = (63-35) / 15

                                              = 28/15

                                             = 1   13/15 min

Sandeep took more time by 1   13/15 min
