Write 215% as a decimal and as a fraction.

I think the answer to this question will help you solve this: http://web2.0calc.com/questions/utopia-has-a-population-of-17-000-if-70-of-the-population-voted-in-the-last-presidential-election-how-many-people-voted-in-the-election_1

Try using the method I used to turn 215% into a fraction and a decimal (dont forget to reduce the fraction if you can!)

If you have any other troubles, let me know.
