Picture this: you’re strolling through the bustling streets of Hanoi’s Old Quarter, the aroma of street food filling the air, and you spot a beautiful silk scarf. The vendor tells you it’s 30% off. Sounds like a great deal, right? But how much will you actually save? Understanding percentages can help you navigate these situations and much more!
What is a Percentage?
In essence, a percentage is a fraction out of 100. The word itself originates from the Latin “per centum,” meaning “by the hundred.” It’s a way to express a part of a whole, making it easier to compare and understand proportions.
Let’s say you ate 5 slices from a pizza cut into 10 equal slices. You ate 5/10 of the pizza, which translates to 50/100, or 50%.

How to Calculate Percentages?
Calculating percentages is simpler than you might think. Here are a few practical methods:
1. Using Decimals:
- To convert a percentage to a decimal: Divide the percentage by 100. For example, 25% is equal to 25/100 = 0.25.
- To convert a decimal to a percentage: Multiply the decimal by 100. For instance, 0.6 is equivalent to 0.6 x 100 = 60%.
2. Using Fractions:
- To convert a percentage to a fraction: Place the percentage over 100 and simplify. For example, 40% is 40/100, which simplifies to 2/5.
- To convert a fraction to a percentage: Divide the numerator by the denominator and multiply by 100. For instance, 3/4 is (3/4) x 100 = 75%.
3. Calculating Percentage Change:
Percentage change helps determine the increase or decrease in a value over time.
Formula: [(New Value – Old Value) / Old Value] x 100
Example: Let’s say the cost of a bowl of Pho in Hoan Kiem district increased from 50,000 VND to 55,000 VND. The percentage change would be [(55,000 – 50,000) / 50,000] x 100 = 10%.
