Answer this question:The ratio of fuel used in gallons to the distance covered in miles by Haley's car is 4:7. If Haley's car used 44 gallons of gas, calculate the distance it covered in miles.
The total ratio representing fuel consumption and distance traveled is 4 + 7 = 11. If 4 / 11, which is the fraction representing fuel consumption, represents 22 gallons of gas, then 7 / 11 representing distance covered represents 7 / 11 * 44 * 11 / 4 = 77 miles.
The answer is 77.

Answer this question:Lois has 40 books. She gives a fourth of her books to her nephew. From her remaining books, she donates a third of her books to the library. Then she purchases 3 new books from the book store. How many books does Lois have now?
Lois gives 40 / 4 = 10 books to her nephew. Then Lois has 40 - 10 = 30 books. Lois donates 30 / 3 = 10 books to the library. Then Lois has 30 - 10 = 20 books. After purchasing new books, Lois has 20 + 3 = 23 books.
The answer is 23.
