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
