Understanding Percentages
What is a Percentage?
A percentage is a way of representing a part of a whole as a fraction of 100. The word “percent” comes from the Latin “per centum,” meaning “out of one hundred.” So, 1.5 percent means 1.5 out of every 100.
The Symbol “%”
The symbol “%” is used to represent “percent.” When you see 1.5%, it means 1.5 out of every 100. This symbol is a shorthand way of expressing percentages.
Relationship to Fractions and Decimals
Percentages, fractions, and decimals are all interconnected. 1.5% is equivalent to 1.5/100 as a fraction and 0.015 as a decimal. Understanding this relationship is key to converting between different representations.
Methods for Calculating 1.5 Percent of 100
There are a few different methods you can use to calculate 1.5 percent of 100, each with its own advantages and disadvantages.
Method 1: Using the Decimal Form
This method involves converting the percentage to a decimal and then multiplying it by the whole number. Here’s how it works:
- Convert the percentage to a decimal: To convert 1.5% to a decimal, divide it by 100. This gives us 0.015.
- Multiply the decimal by the whole number: Multiply 0.015 by 100. This results in 1.5.
Therefore, 1.5 percent of 100 is 1.5.
Method 2: Using the Fraction Form
This method involves converting the percentage to a fraction and then multiplying it by the whole number. Let’s see how it works:
- Convert the percentage to a fraction: 1.5% is equivalent to 1.5/100.
- Simplify the fraction: The fraction 1.5/100 can be simplified by dividing both the numerator and denominator by 0.5. This gives us 3/200.
- Multiply the fraction by the whole number: Multiply 3/200 by 100. This results in 1.5.
As you can see, using either method, we arrive at the same answer: 1.5 percent of 100 is 1.5.
Understanding the Concept
Calculating a percentage can be understood as finding a part of a whole. In our case, 100 represents the whole, and 1.5 percent represents the part we want to find. Essentially, we are dividing the whole into 100 equal parts and then taking 1.5 of those parts.
