Scaling the Mona Lisa

In real life, the Mona Lisa measures  feet by  feet. A company that makes office supplies wants to print a scaled copy of the Mona Lisa on the cover of a notebook that measures 11 inches by 9 inches.
  1. What size should they use for the scaled copy of the Mona Lisa on the notebook cover?
  2. What is the scale factor from the real painting to its copy on the notebook cover?
  3. Discuss your thinking with your partner. Did you use the same scale factor? If not, is one more reasonable than the other?
