Question

Vidya bharti school starts at 10:30 am and is over 4:15 pm if there are two recess periods of 15 minutes and 30 minutes respectively, find the ratio of the recess time to total lesson time of the school

Answer 1

Answer:

3:20

Step-by-step explanation:

Total school time = 5hr 45 minutes = 5 * 60 + 45 = 345 mins

Recess time = 15 + 30 = 45 minutes

Total lesson time = school time - recess time

                              = 345 - 45 => 300 mins

Now, Ratio = recess time / lesson time

                   = 45/300 => 3/20 = 3:20

Things to remember: For finding ratio, both the items should be in same SI unit.
