**How to Calculate Constant of Proportionality?**

**Constant of Proportionality is defined as the fixed value of the ratio between proportional quantities. The constant of proportionality is usually expressed by k. It is also known as a unit rate.**

**The Constant of Proportionality is given by the formula ****B = k / A where A is the initial value and K is the proportionality constant**

**Solved Example:**

**Find the Constant of Proportionality for direct and indirect variation initial value = 10 units, constant of proportionality k = 5**

**Solution:**

**Constant of Proportionality, ****B = k / A**

**= 5 / 10**** **

**= 0.5**

Similarly, you can try the calculator to find the constant of proportionality for

**1. A = 20, k = 15**

**2. A = 34, k = 65**
