Michael finished coloring a picture in 7/12 hour. Vaibhav finished colouring the same picture in 3/4 hour. Who worked longer? By what fraction was it longer?

Time taken by Michael to colour a picture = hour


Also,


Time taken by Vaibhav to colour a picture = hour


First of all we have to convert them into like fractions, we get:


= =


Since,


>


Therefore,


Vaibhav worked for longer period of time


Hence, the difference =


=


=


=


Therefore,


Vaibhav worked for longer period of time by a fraction of
