Get out that calculator or try using your mind to solve these fractional math problems. Some of them are difficult, because they involve simplifying fractions in to decimals, but you don't have a lot of time to do that. The angry looking block that you will be controlling will move around. You have to touch the fraction or decimal and then more over to touch the correct matching decimal or fraction. This will keep your mind fresh by giving you a lot of problems for you to think about.
