Answer 14

Dear Juliette: thou shall not use a calculator to do fractions, because they can round off incorrectly or give recurring decimals which will make your answers incorrect.
You are learning to work with fractions, so do use pencil and paper!

However, you are lucky in this case because -0.9 converts well into -9/10 (which you should know how to do...lol)
