Question

Rohan finished coloring a picture in 37/12 hour. Kartik finished coloring the same picture in 2 ¾ hour. Who worked longer? By what fraction was it longer? Justify your answer.

Answer 1

Step-by-step explanation:

Time taken by Rohan = 37/12 hr

time taken  by Karthik = 2 3/4 hr = 11/4 hr = 33/12 hr

37/12 > 33/12 hrs

37/12 - 33/12 hrs = 4/12 hrs =1/3 hrs = 20 mins

So, Rohan worked longer by 1/3 hrs or 20 mins
