Creating tasks in Russian
The user wants five tasks per topic. The topics are "Отношения" (Ratios) and "Пропорции" (Proportions). They also want problems involving ratios of fractions and percentages. So, I'll create sets: 1) Ratios (5 tasks), 2) Proportions (5 tasks), and 3) Ratios with fractions (5 tasks).
Creating tasks on ratios and percentages
The user asked for five tasks on each topic. So I'll make four sets: 1) Ratios (5 tasks), 2) Proportions (5 tasks), 3) Ratios with fractions (5 tasks), and 4) Ratios and percentages (5 tasks). They didn't request solutions, just the tasks, so I'll provide that as a concise list in Russian with varied difficulty.
Crafting ratio and proportion tasks
Let's make sure the tasks are clean with mathematical notation but not overloaded with text. For ratios, tasks could include simplifying ratios (144:180), solving for unknowns (5:x = 20:16), or practical ratio problems like dividing items in specific ratios. For proportions, we could check if ratios are equal (8:12 = 2:3). I'll ensure everything is consistent without needing solutions.
Creating fraction and percentage ratio tasks
For ratios of fractions, I'll create tasks like simplifying ratios (3/4 : 9/8) or solving for unknowns (1/2 : x = 3:5). For word problems, I'll include examples like mixing ingredients or finding ratios between boys and girls in a class. Lastly, I'll connect ratios with percentages, like calculating men's percentage in a group or a price increase. I'll keep the tasks clear and varied in difficulty.
Creating ratio tasks
I'll create 20 tasks, divided into four sections:
- Ratios – Examples include simplifying ratios, finding x, or solving for amounts in word problems.
- Proportions – Testing proportional relationships or solving for unknowns.
- Ratios of fractions – Simplifying or solving for unknowns with fractional ratios.
- Ratios and percentages – Connecting percentage calculations to ratios, often using word problems for more context.
I'll keep the ratio work mathematically consistent and clear for optimal learning!
