Say:
One kid completed 3/8 of a homework assignment that has 24 problems. Some other kid completed 4/15 of a homework assignment that has 30 problems. Which kid completed more homework problems?

One kid completed 3/8 of a homework assignment that has 24 problems. 3/8 = 9/24; it means the kid completed 9 of 24 problems.
Some other kid completed 4/15 of a homework assignment that has 30 problems. 4/15 = 8/30; it means the kid completed 8 of 30 problems.
It seems that 'One kid' completed more homework problems than 'the other kid'; no matter how much problems the kid has, the kid should complete them as many as possible.
