I need to do this fast because tomorrow I got math exam and suddenly my friend said that scale factor is tested (Basic ones)None of my friend understands...But my question is
1.If I were to get a scale of $x:y$,will my scale factor be $\frac{x}{y}$ or $\frac{y}{x}$?
2.Must scale factor be bigger than 1?
That is the only 2 question I need.Thanks!If you can give me more advice,I would be glad!Even Google search only give examples.Not directly to this question :/
