Answer 2

Answer:

a) Vaibhav Worked Longer

b) Vaibhav Worked longer by 1/6 hours

Step-by-step explanation:

Michael Finished work in = 7/12 Hour

Vaibhav Finished work in = 3/4 Hour

To find which number is greater or smaller, we will make their denominator equal

Common Denominator = LCM of 12 and 4

= 2 x 2 x 3

=4 x 3 = 12

So 3/4 = 3/4 x 3/3 = 9/12

9/12 is greater than 7/12

Therfore Vaibhav Worked Longer

b) Difference in hours

= 3/4 - 7/12

= 9/12 - 7/12

= 2/12

=1/6 Hours

Vaibhav Worked Longer by 1/6 Hours
