Question

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?

Answer 1

Answer:

Vaibhav, $\frac{1}{6}$

Step-by-step explanation:

time taken  by Michael to finish the work=$\frac{7}{12}$

time taken  by Vaibhav to finish the work=$\frac{3}{4}$

                                                                    =$\frac{3}{4} \times \frac{3}{3} =\frac{9}{12}$

since in  $\frac{7}{12}$  and  $\frac{9}{12}$ ,denominator of both the numbers are equal but numerator of $\frac{9}{12}$ is greater than $\frac{7}{12}$. so $\frac{9}{12}$ is greater and hence Vaibhav takes longer times to complete the work by fraction= $\frac{9}{12}$ - $\frac{7}{12}$

=$\frac{2}{12}$ = $\frac{1}{6}$

Answer 2

Answer:

Vaibhav finished more and by 1/6 hours

Step-by-step explanation:

Michael finished colouring in = 7/12 hours.

Vaibhav finished colouring in = 3/4 hours

Vaibhav coloured more and by 1/6 hours
