Answer 2

Tom worked for 3/8 hours. While Jerry worked for 7/12 hours. Who worked more and by how much??

Step-by-step explanation:

• First take out the LCM of denominators of both the fractions.

= LCM of 8 and 12 = 24

= 3/8 x 3/3 = (3 x 3)/ (8 x 3) = 9/24

= 7/12 x 2/2 = (7 x 2)/ (12 x 2) = 14/24

Therefore, 9/24 < 14/24

Hence, Jerry worked more then Tom

by how much= 14/24 - 9/24

= (14-9)/24

= 5/24

Therefore, Jerry worked more than Tom by 5/24 hours.
