## 11.4 Ratio and Proportion

Direct proportion is the relation between two quantities where the ratio of the two is equal to a constant value, while Inverse proportion is the relationship between two variables when their product is equal to a constant value. When the value of one variable increases, the other decreases. In this section, we learn about direct proportion, indirect proportion, description of linear relationship, description of nonlinear relationship. In this section, you learn about Direct proportion, indirect proportion, description of linear relationship, description of nonlinear relationship..
