About NCERT Class 8 Maths Chapter 13 Direct and Inverse Proportions 

 

• Direct Proportion: Two quantities x and y are said to be in direct proportion if they increase (decrease) together in such a manner that the ratio of their corresponding values remains constant. 
• a and b will be in direct proportion if ab = k (k is constant) or a = kb
• Methods to solve problems of direct proportion: 

1. Tabular method: We know that, 

So, if one ratio is given then we can find the other values also. (The ratio remains constant in the direct proportion).

1. Unitary method: We can use the following relation to solve a problem:

ab = k or a = kb

• Inverse Proportion: Two quantities x and y are said to be in inverse proportion if an increase in x causes a proportional decrease in y (and vice-versa) in such a manner that the product of their corresponding values remains constant. 
• a and b will be in inverse proportion if k= ab
• When two quantities a and b are in inverse proportion then they are written as a = 1b
