jack spends 1 2/3 as longer on his homework as Jill
last week, Jill spent 5 1/2 hours doing homework
How long did jack spend doing homework?
The week before jack spent 24 ½ hours doing homework
How long did jill spend doing homework

5/3 * 11/2 = ?
24.5 = 5/3x
Multiply both sides by 3 and divide both sides by 5 to find x (Jill's time).
