Question

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

Answer 1

Answer:

Vaibhav worked longer by 1/6 hours.

Step-by-step explanation:

To find who worked longer,

7/12, 3/4

=LCM of 12,4 = 12,

=7/12, 3/4×3/3,

=7/12, 9/12

=7/12 < 9/12

=7/12 < 3/4

Therefore, Vaibhav worked longer.

To find by what fraction Vaibhav worked longer,

=3/4 - 7/12,

=9/12 - 7/12,

=2/12

=1/6 hours

Answer 2

Step-by-step explanation:

${\huge{\boxed{\sf{\green{❥✰Question✰}}}}}$

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

${\huge{\boxed{\sf{\pink{★✰Answe࿐✰★}}}}}$

Given:-

Time taken by Michael=

$\frac{7}{12}$

Time taken by Vaibhav=

$\frac{3}{4}$

$\frac{7}{12} and \: \frac{3}{4}$

LCM of 12 and 4= 12

$\frac{7}{12} \times \frac{1}{1} = \frac{7}{12} \\ \frac{3}{4} \times \frac{3}{3} = \frac{9}{12}$

Time taken by Michael to finish colouring=

$\frac{7}{12}$

Time taken by Vaibhav to finish colouring=

$\frac{9}{12}$

Maximum time taken=

$\frac{7}{12} < \frac{9}{12}$

More , Time was taken by Vaibhav to complete his colouring.

How much more Time was taken:-

Time taken by Vaibhav- Time taken by Michael

=> 9-7/12

=> 2/12
