Given
- Michael finished colouring a picture in 7/12 hour
- Vaibhav finished colouring the same picture in 3/4
To find:-
- Who worked longer?
- By what fraction was it longer?
SOLUTION
Michael finished colouring = 7/12
Vaibhav finished colouring = 3/4
To find who take longer time , we have to make their denominator same.
L.C.M of 12 and 4 is 12....
= (7/12) × (1/1) = 7/12
= (3/4) × (3/3) = 9/12
= (7/12) < (9/12)
Hence, (7/12) < (3/4)
So, Vaibhav worked for longer time.
______________________________
Therefore, Vaibhav worked for longer time by (1/6)
