Ratios and fractions are important ideas in Year 9 math. They help us understand how things compare, make choices, and solve problems that involve scaling.

What Are Ratios?

• Cooking and Recipes: Imagine a recipe that needs a ratio of ingredients like 2:3. If you double the recipe, you would use a ratio of 4:6. This shows you understand how to adjust amounts in the right way.
• Sports Statistics: When we look at a player's performance in sports, we often see ratios. For example, the ratio of goals scored to games played helps coaches evaluate how well a player is doing.

What Are Fractions?

• Financial Literacy: Knowing about fractions is super important for managing money. For example, if you spend 25% of your budget on rent, that means you are spending one-fourth of your total expenses.
• Data Interpretation: Fractions also help us understand survey results. If 60 out of 200 students prefer a certain subject, that fraction (60/200) simplifies to 3/10. This tells us that 30% of the students like that subject.

By learning how ratios and fractions work together, Year 9 students can build important problem-solving skills. These skills help not just in school, but also in everyday life.
