This is a compilation of worksheets about percentage. Each worksheet has an item that contains (1) a completely solved solution, (2) a partially solved example where parts of the solution are filled in by the student. (3) and lastly, a number of questions where they need to figure out the whole solutions by themselves.
Just like most math problems, there are a number of ways to solve them. Solutions to some of the examples here are just one of the many possible ways to solve them.
I have used this packet to work with my students for 2 weeks. Depending on how the class as a whole are doing, you can use this for reference for the whole Percentage topic.
