It is very common to come across situations in life that will require you to calculate percentage change. For example, a salesman made **12** sales in January and **9**** **sales in February. They might want to calculate the changes in terms of percentage increase or decrease to have a clear picture of how the business is performing.

**9 – 12 = -3**

**Step 2:** Once you subtract the old number from the new number, you need to divide the result **-3** by the old/original number **12**

**-3 ****¸**** 12 = -0.25**

**Step 3:** Multiply the answer **-0.25** by **100** to convert it into a percentage
