This worksheet gives the students a fraction to scale up (by any factor of their choice) and scale down (simplest form), showing that each of the fractions are equivalent. I ask my students to show what number they multiplied and divided by to get the equivalent fractions. It is a good introduction lesson for ratios, rates and/or proportions.
Once the students understand the concept they are asked to make up their own problems, encouraging them to think at a higher level.
