This is a great preparation guide for reviewing fractions, decimals and percents. It is has thorough explanations and examples that are concise and to the point. I would recommend it to anyone who needs a basic general review and also for those who have to prepare for math tests. Using and practicing the examples in this guide will help the students target their weak areas of math so that they can identify and specifically practice those areas of weakness. I would recommend it as a solid math review/test preparation on the basic maths.
