How to use percentages in managing your life?

In the Kitchen
If you want to decrease or increase quantities of ingredients in a particular recipe by a specific percentage.
In Health
Track your weight loss progress or determine your body fat percentage over time.
Quick tips for understanding percentages:
- Always remember: A percentage means "per hundred," so 25% is simply one-quarter of the value.
- Double discount: 20% then 10% isn't 30%. Use a calculator to find the exact final price.
- Increase vs Decrease: A 10% increase followed by a 10% decrease won't bring you back to original price!
