Michael finished colouring 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?

Solution:

Let's compare the fractions and decide which one is larger.

Time is taken by Michael = 7/12 hour

Time is taken by Vaibhav = 3/4 hour

= (3×3) / (4×3) (converting into like fractions)

= 9/12 hour

Since, 9/12 > 7/12

Therefore, Vaibhav worked for longer.

Difference = 9/12 − 7/12

= 2/12

= 1/6  hour

Thus, Vaibhav took 1/6 hour more than Michael.
