### Ratios & Proportions book has been updated!

Math Mammoth Ratios, Proportions & Problem Solving is a worktext that concentrates, first of all, on two important concepts: ratios and proportions, and then on problem solving. It is meant for grades 6-7.

This book has been now updated to include many new lessons that will ALSO be in the upcoming Math Mammoth grade 7-B. This means that you can use it to continue pre-algebra studies after finishing 7-A.

See free samples and more info:

For now, I've kept the download price at $5.00 though the book became quite a bit longer.
