Question 174684: Here is a difficult word problem I am struggling with:
8-year-old Samantha visited Santa at a local department store. He gave her this riddle:
" I started working at 15. I spent 1/4 of my working life in a factory. I spent 1/5 of my working life in an office, and I spent 1/3 of my working life as a school caretaker. For the last 13 years of my working life I've been Santa Claus. How old am I?"
The problem says you need to explain how you got the answer and how you know it is correct.
I am not sure how to explain either of those things! What operations could you do? How do you figure this problem out overall?
Thanks!
