This guide provides a comprehensive overview of algebraic ratio problems... Show more
This section provides practice problems for converting between equivalent ratios and fractions. Students are asked to complete a series of exercises that reinforce the relationship between ratios and fractions.
Vocabulary: Equivalent ratios are ratios that represent the same relationship between quantities, just expressed with different numbers.
The exercises include:
Example: 4:6 = 10:15 can be written as equivalent fractions 4/6 = 10/15, which simplifies to 2/3.
This page provides the solutions to the previous exercises, allowing students to check their work and understand the correct approach to solving these problems.
Highlight: All ratios and fractions are given in their simplest form, reinforcing the importance of simplification in ratio and fraction work.
The solutions demonstrate how to:
This section introduces the technique of using equivalent fractions to solve for unknown variables in ratios. Two worked examples are provided to illustrate the process.
Example: For the ratio 4:12 = 10:x, we can write it as equivalent fractions 4/12 = 10/x, then solve for x to get x = 30.
Example: For the ratio y:18 = 5:30, we can write it as equivalent fractions y/18 = 5/30, then solve for y to get y = 3.
These examples demonstrate how to:
This page provides a set of practice problems for students to apply the technique of solving for unknown variables in ratios using equivalent fractions.
Highlight: These problems are designed to reinforce the skills learned in the previous section and provide varied practice with different ratio structures.
The problems include ratios with:
This page presents the solutions to the practice problems from the previous page. It allows students to check their work and understand the correct approach to solving these types of problems.
Highlight: Each solution is given as a single numerical value, emphasizing the importance of solving for the specific unknown variable.
The solutions demonstrate:
This section introduces a more advanced application of the equivalent fractions method, where students learn to express one variable in a ratio in terms of the other.
Example: For the ratio y:8 = 3:x, we can express y in terms of x as y = x, and x in terms of y as x = y.
Example: For the ratio 7:y = x:2, we can express y in terms of x as y = , and x in terms of y as x = .
These examples show how to:
This page provides a set of practice problems for students to apply the technique of expressing one variable in a ratio in terms of the other using the equivalent fractions method.
Highlight: These problems require students to produce two expressions for each ratio, one for each variable in terms of the other.
The problems include ratios with:
This page presents the solutions to the practice problems from the previous page. It allows students to check their work and understand the correct approach to expressing variables in terms of each other in ratios.
Highlight: Each solution provides two expressions, one for x in terms of y and one for y in terms of x, emphasizing the reciprocal nature of these relationships.
The solutions demonstrate:
This section focuses on simplifying ratio expressions and writing them in standard forms. It introduces the concept of expressing ratios in the form x:y = a:b, where a and b are constants.
Example: For the ratio y:4 = x:5, we can express it as x:y = 5:4.
Highlight: This form of expression allows for easy comparison of ratios and identification of proportional relationships.
The example demonstrates how to:
This page provides additional examples and practice with simplifying ratio expressions and writing them in standard form. It reinforces the concepts introduced in the previous section.
Example: For the ratio x:y = 4:7, we can derive that 7x = 4y.
Highlight: This section emphasizes the connection between ratio expressions and algebraic equations.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
