Percent of decreaseJust like the name suggests, the percent of decrease is the amount of decrease out of one hundred. Thus, the formula to use is : Amount of decrease / Original amount I will illustrate what I just said with examples. Example #1: Find the percent of decrease from 6 to 4. Amount of decrease is 6 − 4 = 2 Original amount is 6 2 / 6 = 0.3333 multiply 0.3333 by one hundred to get the answer as a percent. 0.3333 × 100 = 33.33, so the answer is 33.33%. Example #2: Find the amount of decrease per hundred from 10 to 5. Amount of decrease is 10 − 5 = 5 Original amount is 10 5 / 10 = 0.50 multiply 0.50 by one hundred to get the answer as a percent 0.50 × 100 = 50, so the answer is 50%. Example #3 Find the amount of increase per hundred from 4 to 8. Amount of decrease is 4 − 8 = 4 + 8 = 4 Original amount is 4 4 / 4 = 1 multiply 1 by one hundred to get the answer as a percent 1 × 100 = 100, so the answer is 100%.
