I need help editing a math book on fractions and decimals.

I need help from an expert in math to edit a children's math book about fractions and decimals. Your task would be to read the document in general and give feedback. Additionally, look at the step by step explanations and suggest better explanations and/or alternate methods. I don't want you to rewrite the book, just give your expert opinion on the content and fill in any gaps that would keep the reader from understanding the material. Also, correct any incorrect or misleading information that I may have overlooked. I am just looking for you to send a Microsoft Word document or Google docs with your suggested edits. Is this something you can help me with?
