Question: Find the answer to this math problem: Maggie spent a quarter of her money, while Riza spent one-third of her money. They each had $60. How much money do the two of them have left?
Answer: 
Maggie spent $60/4 = $15.
So, Maggie is left with $60 - $15 = $45.
Riza spent $60/3 = $20.
So, Riza is left with $60 - $20 = $40.
Thus, they have a total of $45 + $40 = $85 left.
