Chapter 6: Operations and Uses of Ratios, Proportions, & Percents

This chapter has everything you need to know about ratios, proportions, and percents! You will start out learning what ratios, rates, and proportions are and the operations and word problems involving them. From there, you will study how to solve proportions involving variables and then use these proportion solving skills in your travels through similar figures and scale factors. The second half of the chapter is devoted to mastering percents. From the foundations of converting between fractions, percents, and decimals to finding percents, the part, or the whole, through to calculating percent of change, you will leave this chapter knowing percents and how to use them in any way you could possibly need them in Pre-Algebra and beyond! What are you waiting for?! Strengthen your skills and get started!!

  • positive review  I can't say enough good things about Mr. Groden! He has helped my son so much. My son fights working with tutors but Mr. Groden did an excellent job pairing with my son and making him feel comfortable with him. He really understands the areas that my son struggles with and helps him in those areas while at the same time giving my son positive feedback and encouraging him. It gives me peace of mind knowing that with Mr. Groden's help my son will do well and grow and learn and be successful in his math classes!

    Matt is amazing! Both of my children see him weekly and they love when he comes to tutor. He is extremely knowledgeable and has a different perspective on teaching math the the kids really get excited about. I don't think I have met anyone more enthusiastic about math, ever. It's inspiring for the kids to work with someone that truly loves teaching math!

  • Mr. Groden was definitely the best tutor I've ever had. He makes learning easy and enjoyable and he never makes you feel dumb for asking questions. He's an amazing person and an even more amazing tutor. I would definitely recommend him for anyone struggling with math.

    My son thoroughly enjoyed taking Matt’s summer enrichment pre-calc class. He is a positive upbeat teacher who makes math fun! I would encourage any parent interested in keeping their child engaged in learning to register! He provided my child with renewed excitement in a subject for which he was losing enthusiasm. He had an amazing experience!

  • Mr Groden has the ability to make calculus (and math in general) fun, meaningful, relevant, etc. and to relate complex concepts in a way that not only makes sense, but also gives the students the ability to re-apply the concepts later on. Our son had Mr. Groden as his calculus teacher in high school, and our daughter has now used Mr. Groden's services for both SAT prep and AB Calculus weekly review. Both have been excellent and more than worth the money spent.

    Matt’s excitement for learning boosted my sons confidence. He showed him ways to solve problems and feel confident. That in itself is amazing. I highly recommend Matt. No doubt your child’s grade or SATs will soar.

    My daughter had a great experience in Mr. Groden's SAT prep class. We had been searching for an effective affordable option and this in person class was just the right choice!! Excellent follow up and communication of expectations each week prior to class helped the kids keep on track. It also helped me know what was covered and what was expected of her. Nice work! I highly recommend!

  • Matt Groden is the best teacher, academic or otherwise, I've had the privilege of studying under. His passion and dedication to his craft as an educator allow him to take difficult subjects and make them somehow enjoyable. He challenges his students to rise to meet their challenge, and invests personally in their success. He possesses a unique gift to help students visualize and understand mathematical concepts and problems, in addition to the patience and commitment to make sure his students are prepared for what's coming their way. His lessons have impacted my college career in more ways than one, and I'm grateful. If you're looking for a math tutor, there's none better.

    I was lucky enough to have Mr. Groden as my teacher for two classes throughout high school. In school, math was never my strong suite but Mr. Groden was able to use real life examples that pertained to myself that helped me with understanding the math. After a couple of years, I started attending Rider University where I studied Business. I hadn't been in a math class in years so when I found out that I had to take Quantitative Methods for Business, I knew that I was in trouble. After receiving my first test and seeing that I received a low C, I reached out to Mr. Groden to see if he were doing any tutoring and surly enough he was. Mr. Groden met with me once a week and again was able to use real life examples that pertained to myself and I was able to understand the math. I ended the semester receiving an A in the class, and I know 100% I would not have reached that without Mr. Grodens help. Thank you!

  • Both of our sons were extremely fortunate to have Mr. Groden for AP Calculus. He is enthusiastic, clear and an all-around outstanding teacher. He motivates his students and consistently shows great interest in their well being, both in and out of the classroom. Both our sons were extremely well prepared for the AP exam. Thank you!

    Matt has helped my son immensely in preparing both for the SATs and the AP Calculus BC exam. He has a way of explaining and teaching math that kept my son excited and energized to learn more. My son did extremely well on his SATs and was strong in Calculus, all thanks to Matt and his care for his students. If you are need for math help for your child, look no further!

  • positive review  Love. :) My daughter took Matt’s AP Calc prep class, and my son watched the algebra prep videos. Both loved, especially my daughter who now wants to sign up for every class Matt offers. Thank you for approaching teaching in such a fun and engaging way!! So highly recommend. :)

    My son was struggling in Calculus. He lost all confidence and felt there was no way he could pass his class. With Matt's help my son started understanding his work and gained confidence. Matt made learning exciting and fun. We owe so much to Matt's amazing ability to do whatever it takes to help his students. There is no one better than Matt!

  • My son Griffin took Matt's AP Clac summer class he thoroughly enjoyed Matt's style of teaching and felt the class will prepare him for AP Calc this year. I highly recommend Matt and any of his classes!

    positive review  I had Matt Groden for AP Calculus and I have to say, he was and probably will be the greatest teacher I ever had. Not only was he exceptional in terms of his teaching ability and breadth of knowledge, but it is his care for learning was what made him unique. This was the first teacher in a long time that I can remember who valued learning and discovery over just memorizing and ‘teaching to the test’. His ability to make students excited to learn new math material is what makes Matt so perfectly suited for this. Anyone with the chance to learn math with him should most definitely take this opportunity - you will not be disappointed!!

  • My daughter loved working with Matt through his Middle School Math Foundations course. She was apprehensive to take Math for fun over the summer alongside her other activities but absolutely loved Matts approach to teaching! She is sad to see it end but is looking forward to continuing with him throughout her education! Highly recommend Matt to all my friends and family out there!

    positive review  It was like divine intervention when my son ASKED me (I know right??) if he could take a class leading up to honors Algebra 2 in the Fall. That same day I came across Matt’s summer offerings. Matt was the perfect teacher - engaging, passionate and fun - and my son really enjoyed taking his class (ENJOYED math in the summer? I know right?). THANK YOU MATT!! He’s ready 👍

  • Mr. Groden is an outstanding math teacher. He is very patient, always positive and has an excellent reputation. He currently tutors my 8th grader. We would highly recommend him!! He is the best!

    If you are looking for an enthusiastic teacher who makes understanding math easy then look no further. Matt came to our rescue when my daughter was struggling in AP Calculus BC. Not only was he able to boost her grade to an A, she also scored a 5 on her AP exam for both Calculus AB and BC. Also, My son went to his SAT class over the summer and after every class he said how much he enjoyed Matt and was excited about what he learned. I will continue to give Matt the highest recommendation which is rare for me since I am a math teacher myself. He is excellent!
