Deciphering Percentages: More Than Just a Symbol
Before we jump into the calculation, let’s take a moment to understand what “percent” really means. “Percent” originates from the Latin phrase “per centum,” meaning “out of one hundred.” So, when we talk about 65%, we’re essentially referring to 65 parts out of every 100 parts.
Methods to Calculate 65% of 25
Now, let’s explore the different methods to find 65% of 25:
1. The Decimal Method:
- Convert the percentage to a decimal: Divide 65 by 100, resulting in 0.65.
- Multiply the decimal by the number: Multiply 0.65 by 25, which equals 16.25.
Therefore, 65% of 25 is 16.25.
2. The Fraction Method:
- Convert the percentage to a fraction: 65% is equivalent to 65/100.
- Simplify the fraction: Both 65 and 100 are divisible by 5, simplifying the fraction to 13/20.
- Multiply the fraction by the number: (13/20) * 25 = 16.25.
Again, we arrive at the same answer: 65% of 25 is 16.25.
