question: 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 = $<<60/4=15>>15.
  So, Maggie is left with $60 - $15 = $<<60-15=45>>45.
  Riza spent $60/3 = $<<60/3=20>>20.
  So, Riza is left with $60 - $20 = $<<60-20=40>>40.
  Thus, they have a total of $45 + $40 = $<<45+40=85>>85 left.
