Explanation:
Percentages are a way to express a number as a fraction of 100. The term “percent” comes from the Latin phrase “per centum,” meaning “by the hundred.” For instance, 20% means 20 out of every 100. When you’re asked to find a percentage of a number, you’re essentially figuring out how much of that number represents the specified fraction of 100.
To calculate 20% of 55, you follow these steps:
- Convert the percentage to a decimal:
A percentage is converted to a decimal by dividing it by 100. In this case, 20% becomes ( \frac{20}{100} = 0.20 ). - Multiply the decimal by the number:
Once you have the decimal, multiply it by the number for which you’re calculating the percentage. Here, it’s ( 55 \times 0.20 ).
- ( 55 \times 0.20 = 11 )
- Result:
The result, 11, represents 20% of 55. This means that if you take 55 and divide it into 5 equal parts (since 20% is one-fifth of 100%), each part would be 11.
This process can be used to find any percentage of any number. Simply convert the percentage into its decimal form and multiply it by the number you’re interested in. It’s a fundamental concept used in everyday life, from calculating discounts while shopping to understanding statistics or even in various financial calculations.
