Chapter 7: Coordinates, Ratio And Proportion
What you need to learn in this chapter
In this chapter, we will be learning about coordinates, ratio, and proportion. First, we will learn about coordinates in the first quadrant. We will recognize the x-axis, y-axis, and the origin (O). We will also learn how to determine the coordinates of a point in the first quadrant and vice versa.
Next, we will learn about ratio. We will learn how to represent the relationship between two quantities using ratios like 1:1, 1:10, 1:100, and 1:1000.
After that, we will learn about proportion. We will learn how to determine an unknown value using the unitary method.
Lastly, we will practice problem-solving. We will solve problems that involve coordinates, ratios, and proportions in daily situations.
