Question: Alannah, Beatrix, and Queen are preparing for the new school year and have been given books by their parents. Alannah has 20 more books than Beatrix. Queen has 1/5 times more books than Alannah. If Beatrix has 30 books, how many books do the three have together? Think carefully first, then make a decision:
If Beatrix has 30 books, Alannah has 30 books + 20 books = 50 books. Queen has 1 / 5 * 50 books = 10 more books than Alannah. The total number of books Queen has is 50 books + 10 books = 60 books. All three have 60 books + 50 books + 30 books = 140 books together. So the answer is 140.
