1. Inverse Proportion

Two quantities such as a and b are said to be in Inverse proportion if

• Increase in a decreases the b
• Decrease in a increases the b

However, the ratio of their respective values shall be the same.

• a and b will be in inverse proportion if k= ab
• In such a case if b₁, b₂ are the values of b corresponding to the values a₁, a₂ of a respectively then, a₁b₁ = a₂b₂ = k, 
• When two quantities a and b are in inverse proportion then they are written as a $\propto \frac{1}{b}$
