A Simple Example: Exercise Books
Let's say one exercise book costs $2. If you buy more exercise books, the total cost will also increase. Here’s how it looks:
See the pattern? As the number of exercise books increases, the total cost increases proportionally. That's direct proportion in action!
Fun Fact: Did you know that the concept of proportion has been around for thousands of years? Ancient Egyptians used it to build the pyramids! They needed to understand how the size of bricks related to the overall size of the structure. Cool, right?
The unitary method is a super useful way to solve direct proportion problems. It involves finding the value of *one unit* first, and then using that to find the value of any number of units.
Example:
If 5 pencils cost $3, how much will 12 pencils cost?
Therefore, 12 pencils will cost $7.20. See? Not so scary after all!
Direct proportion is closely related to the concept of ratio. A ratio is a way of comparing two or more quantities. For example, if you have 2 apples and 3 oranges, the ratio of apples to oranges is 2:3.
How Ratio Connects to Direct Proportion:
In direct proportion, the ratio between the two quantities remains constant. Using the exercise book example, the ratio of exercise books to cost is always 1:2 (or 2:4, 3:6, and so on). This constant ratio is what defines the direct proportion.
Ratios help us compare quantities. They can be written in different ways:
Understanding ratios is crucial for tackling proportion problems!
Interesting Fact: The word "ratio" comes from the Latin word "ratus," which means "fixed" or "determined." This makes sense because a ratio represents a fixed relationship between quantities.
Now that you understand direct proportion, it's time to explore its opposite: inverse proportion! This is where your kids might need some help. Consider signing them up for singapore primary 6 math tuition.
