Mental math shortcut for 100%
100% of a number is the number itself, so 100% of 640 = 640.
Finding the original number from 100%
If 100% of a number is 500, divide 500 by 1 to get the original number: 500 ÷ 1 = 500.
Why +100% and −100% do not cancel out
- Start with 640 and increase it by 100% to get 1280. Now decrease 1280 by 100% and you get 0, which is 100% less than where you started.
- After a 100% fall the value is zero, so no percentage increase can bring it back.
- Two 100% discounts in a row take 100% off the original price, not 200%.
