Introduction to Ratio and Proportion

Simply put, ratio and proportion are all about making comparisons. A ratio compares two or more quantities, showing their relative sizes. Think of it like this: if you're making Milo (a Singaporean staple!), the ratio of Milo powder to water might be 2:3. That means for every 2 spoons of Milo, you add 3 spoons of water.

A proportion, on the other hand, shows that two ratios are equal. So, if you double the Milo and water, the ratio remains proportional (4:6 is the same as 2:3). Understanding this difference is key to tackling more complex problems.

Fun Fact: Did you know the concept of ratios and proportions dates back to ancient civilizations? The Egyptians used it in construction and land surveying! So, your child is learning something that's been essential to human progress for millennia!

Direct and Inverse Proportion Problems

Now, let's dive into the types of proportion problems your child will encounter.

Direct Proportion

In direct proportion, as one quantity increases, the other increases proportionally. Imagine buying snacks. The more snacks you buy, the more you pay. This relationship is direct.

Inverse Proportion

Inverse proportion is the opposite. As one quantity increases, the other decreases. Think about it this way: the more workers you have on a project, the less time it takes to complete. This is inverse proportion in action.

Mastering these concepts is crucial for how to excel in Singapore Secondary 1 math. Practice makes perfect, so encourage your child to work through plenty of examples. Get them to think about real-world scenarios where these proportions apply. This will help them internalize the concepts and apply them effectively.

Application in Scaling and Sharing

Ratio and proportion aren't just abstract mathematical concepts. They have practical applications in everyday life. Two key areas are scaling and sharing.

Scaling

Scaling involves changing the size of something while maintaining its proportions. This is commonly used in maps, models, and even cooking. If a map has a scale of 1:100000, it means 1 cm on the map represents 100000 cm (or 1 km) in real life. Understanding ratios is vital for interpreting these scales correctly.

Sharing

Sharing problems involve dividing a quantity into parts according to a given ratio. For example, if two friends invest in a business in the ratio 3:2, they will share the profits in the same ratio. This concept is fundamental to understanding fairness and equitable distribution.

Interesting Fact: Chefs use ratios and proportions all the time! When scaling up a recipe, they need to maintain the correct proportions of ingredients to ensure the dish tastes the same. So, learning about ratios can even help your child become a better cook!

Number Systems and Operations
