Example: In a class, there are 12 girls and 18 boys. The ratio of girls to boys is 12:18. We can simplify this ratio by dividing both sides by their greatest common factor, which is 6. So, the simplified ratio is 2:3.
Fun Fact: Did you know that the concept of ratios dates back to ancient civilizations? The Egyptians used ratios extensively in their architecture and construction, including the pyramids! Talk about a solid foundation!
A rate is a special type of ratio that compares two quantities with different units. Think of it as a ratio with a "per" in it. For example, speed is a rate – it's the distance travelled per unit of time (e.g., kilometers per hour or km/h).
Example: A car travels 150 kilometers in 3 hours. The rate of travel (speed) is 150 km / 3 hours = 50 km/h.
Interesting Fact: The word "rate" comes from the Latin word "rata," meaning "fixed" or "established." This makes sense when you think about how rates are often used to establish a standard measure, like the price per kilogram of rice.
A proportion is a statement that two ratios or rates are equal. It's like saying two fractions are equivalent. If a/b = c/d, then a, b, c, and d are in proportion.
Example: If 2 apples cost $1, then 4 apples will cost $2. The ratio of apples to cost is the same in both cases (2:1 = 4:2), so they are in proportion.
History: Proportions were crucial for early mapmakers and navigators. They used proportions to scale down large distances onto smaller maps, allowing them to explore and chart the world.
Now that we understand the basics, let's get down to the nitty-gritty of tackling those pesky Secondary 2 ratio problems. Here are some tips to help your child (and maybe even you!) conquer them:
This might sound obvious, but it's the most crucial step. Before even touching your calculator, make sure you really understand what the question is asking. What quantities are being compared? Are they asking for a ratio, a rate, or something else? Highlight keywords and break down the problem into smaller, manageable parts.
Simplifying ratios and fractions is key to making calculations easier. Always try to reduce ratios to their simplest form. This will not only make the numbers smaller but also help you see the relationships more clearly.
The unitary method is a powerful tool for solving proportion problems. It involves finding the value of one unit first, and then using that to find the value of the desired quantity. For example, if 5 pens cost $3, find the cost of 1 pen ($3/5 = $0.60), and then use that to find the cost of 10 pens (10 x $0.60 = $6).
There's no substitute for good old-fashioned practice. The more problems your child solves, the more comfortable they'll become with the different types of ratio, rate, and proportion questions. Encourage them to work through examples in their textbook, past year papers, and online resources. Consistent practice is the key to how to excel in Singapore Secondary 2 Math.
If your child is struggling, don't hesitate to seek help. Whether it's from their teacher, a tutor, or even a knowledgeable friend, getting a different perspective can make all the difference. Remember, asking for help is a sign of strength, not weakness. Consider Singapore Secondary 2 Math tuition to provide targeted support and personalized guidance.

Fun Fact: Did you know that the concept of ratios dates back to ancient civilizations? The Egyptians used ratios to build the pyramids! Talk about practical application!
Model drawing, also known as the bar model method, is a fantastic way to visualize ratio problems. It's especially helpful for those questions that seem confusing at first glance. Here's how it works:
Example: The ratio of apples to oranges in a basket is 3:5. If there are 12 apples, how many oranges are there?
Solution:
Draw a bar representing apples and divide it into 3 equal parts. Since there are 12 apples, each part represents 4 apples (12 / 3 = 4). Draw another bar representing oranges and divide it into 5 equal parts. Since each part represents 4, there are 20 oranges (5 x 4 = 20).
Once you're comfortable with model drawing, you can move on to algebraic approaches. This involves using variables to represent unknown quantities and setting up equations to solve for them.
Example: The ratio of John's age to Mary's age is 2:3. In 5 years, the ratio will be 5:7. How old are John and Mary now?
Solution:
Let John's age be 2x and Mary's age be 3x. In 5 years, their ages will be 2x + 5 and 3x + 5, respectively. We can set up the following equation: (2x + 5) / (3x + 5) = 5/7. Solving for x, we get x = 10. Therefore, John is 20 years old (2 x 10) and Mary is 30 years old (3 x 10).
Interesting Facts: Algebra, with its roots in ancient Babylonian mathematics, provides a powerful symbolic language for expressing and solving complex relationships. Learning algebra is like unlocking a secret code to the universe!

If you want to double the recipe, you simply double both quantities while maintaining the same ratio. Get it? No need to agak-agak (guess) anymore!
Interesting Facts: Ratios in baking aren't just about taste; they also affect the texture of your baked goods. Too much flour, and your cake will be dry; too much sugar, and it might be too dense. So, pay attention to those ratios!
Ever wondered how maps represent vast distances on a small piece of paper? It's all thanks to ratios! A map's scale, like 1:100,000, means that 1 cm on the map represents 100,000 cm (or 1 km) in the real world. This allows you to measure distances accurately on the map and translate them to actual distances. Scale models, like those miniature airplanes or cars, also use ratios to accurately represent the real thing in a smaller size.
Subtopic: Understanding Map Scales
Map scales can be expressed in different ways: as a ratio (1:100,000), as a fraction (1/100,000), or as a verbal statement (1 cm represents 1 km). Learning to convert between these formats is a valuable skill for understanding and using maps effectively.
History: The use of scale models dates back to ancient times. The Romans, for example, used scale models to plan and design their cities and buildings. Imagine trying to build the Colosseum without a proper scale model!
