Proportions Test

Proportions hide inside very different problems: map scale, solution concentration, speed and time, working together. This test checks whether you can recognise a proportional relationship and work with it confidently.

Question types

• Proportion problems. Motion, work, mixtures — turn the text into a proportion.
• Direct proportion. Two values grow together; find the unknown value.
• Scale. Convert map and drawing scale into real sizes.
• Inverse proportion. One value grows at the expense of another — don't mix them up.

Difficulty levels

• Easy — more than 100 tasks. Direct relationships and simple ratios.
• Medium — more than 200 tasks. Motion, work and mixture problems.
• Hard — more than 70 tasks. Combined conditions with several steps.

Available languages

• 7 languages: English, Русский, Español, 中文, Deutsch, Қазақша, Français

Who it is for

• Students in grades 6–9, where proportions appear constantly.
• Anyone preparing for exams and wanting stable results on motion and work problems.
• Adults refreshing the skill before a course or professional exam.
