This page presents three questions covering direct and inverse proportion problems. The questions involve calculating values based on given proportional relationships.
Example: Question 1 deals with y being directly proportional to the square of x, where y = 24 when x = 2.
Vocabulary: Direct proportion - a relationship where one quantity increases at the same rate as another.
Vocabulary: Inverse proportion - a relationship where one quantity decreases at the same rate as another increases.
This page focuses on a more complex direct proportion problem involving the relationship between H and c, where H varies directly to the cube of c.
Example: When H = 40, c = 2, students are asked to express H in terms of c, find H when c = 5, and find c when H = 5000.
Highlight: The question demonstrates how to manipulate equations involving cubes in direct proportion problems.
This page presents a problem involving inverse proportion between force and distance in the context of magnetism. Students are asked to express the relationship mathematically and solve related problems.
Example: The force F exerted by a magnet is inversely proportional to the square of the distance d .
Highlight: The question includes an explanation of what happens to F when d is halved, reinforcing understanding of inverse proportion.
This page contains two problems involving inverse and direct proportion. The first deals with inverse proportion between A and B, while the second involves direct proportion between C and the square root of y.
Example: In the first problem, A is inversely proportional to B, and students must find A when B = A.
Highlight: The second problem introduces direct proportion with square roots, expanding on previous concepts.
This page presents a practical application of inverse proportion in the context of airport check-in times. It demonstrates how the time taken for check-in is inversely proportional to the square of the number of staff working.
Example: Students must find an equation connecting time and staff number , and determine the minimum number of staff needed for a specific check-in time.
Highlight: This question shows how inverse proportion can be applied to real-world scenarios, enhancing students' understanding of its practical uses.
This page features a complex problem involving both direct and inverse proportion relationships. Students must navigate multiple proportional relationships to solve for the final value.
Example: The problem involves variables a, w, and c, with a directly proportional to √c and w inversely proportional to a³.
Highlight: This question tests students' ability to handle multiple proportion relationships simultaneously, preparing them for more advanced mathematical concepts.
This page presents a practical application of inverse proportion in the context of research planning. Students must determine the number of researchers needed to complete a project in a given time frame.
Example: The number of days to complete research is inversely proportional to the number of researchers .
Highlight: This question demonstrates how inverse proportion can be used in project management and resource allocation scenarios.
The final page of the document challenges students to match different graphs to their corresponding proportional relationships. This exercise tests students' ability to visually interpret various types of proportion.
Example: Students must match graphs to relationships such as y = 1/x, y = √x, and y = x².
Highlight: This question helps students develop a visual understanding of how different proportional relationships appear when graphed, reinforcing their conceptual knowledge.

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.
