Manga Math Mysteries 5: The Ancient Formula - Fractions

A puzzle left behind by Sifu Faiza's grandfather has everyone stumped. A circle divided into wedges shows part of the formula for an ancient medicine. But some of the wedges are blank, and no one knows how or why the original formula disappeared! Joy, Adam, Amy, and Sam will have to use clues—and fractions—to discover the truth about . . . The Ancient Formula.

“"This title demonstrates the use of mathematics in scientific discovery. For the middle school student embarking on the exploration of multiplication and division, the book is a nice read. The presentation of the topics does not separate the mathematics from the story. The illustrations are great and provide good visual aids to understanding how sets are used in calculations. The story illustrates both the importance of using the scientific method to find solutions to problems and the dangers of hasty generalizations. Overall, this title presents accurate information with an appeal to middle school/junior high students. The book is probably best used for general awareness of mathematical principles. The information presented does not have the technical treatment needed to classify the book as a reference work; however, it is a fun read, and readers who are just learning about multiplication and division or who have recently learned these topics could begin to understand the usefulness of mathematics in problem solving." --Science Books & Films”
