2 Fractions

The following 10 sets of fraction problems will provide you with exercises in how to convert fractions and how to do arithmetic problems that involve fractions. (Sections 3 and 4 deal with decimals and percentages, which are also actually fractions, but are called something else for

clarity.) In order to understand arithmetic, it is important to practice and become comfortable with fractions and how they work.

You will start off with questions that just deal with numbers. After you’ve had a chance to practice your basic fraction skills, you can move on to some word problems involving fractions.
