Olivia ordered 11 2/3 pounds of books.
How to solve:
*Turn 2 1/3 into an improper fraction by doing denominator x whole number + numerator, so 3 x 2 + 1 which is 7/3.
* Multiply both fractions by doing numerator x numerator and denominator x denominator.
*This gives you 35/3 and now you just simplify by seeing how much times 3 can go into 35 so it is 11 times and 2 left over, so it is 11 2/3
