My son came home with this math problem and while I have a clue to day to day math it has been 100 years since I have been in a class room. Can you help please?

Mrs. Freeman invested a fourth of her money in stocks, a fifth in a frozen yogurt store, and a sixth in her child's college fund. She put the remaining $32,000 in the bank. What is the total amount she has invested or saved.

Thanks for looking
