Understanding fractions and their conversion into percentages is an essential math skill that finds application in various real-life scenarios, from calculating discounts while shopping to figuring out how well you did on a test. Today, let's dive into the seemingly simple, yet surprisingly versatile world of converting 13/20 to a percentage ๐.
๐งฉ What is a Fraction and a Percentage?
Before we jump into the conversion process, let's understand the basics:
Fractions
A fraction represents parts of a whole. The number above the line, called the numerator, indicates the number of parts we have, while the number below the line, known as the denominator, tells us how many parts make up the whole.
Percentages
A percentage is a fraction expressed as a part of 100. For example, if you have 50%, you're talking about 50 out of 100, or 50/100, or 1/2 when simplified.

๐ The Method: Converting 13/20 to a Percentage
Now, let's proceed with the conversion:
-
Start with the Fraction: We have 13/20.
-
Convert to a Decimal: Divide the numerator by the denominator:
13 รท 20 = 0.65
-
Convert to Percentage: Multiply the result by 100 to get the percentage:
0.65 ร 100 = 65%
So, 13/20 is 65%.
Important Note:

-
Recognize Common Fractions: Familiarize yourself with common fractions and their percentage equivalents:
Fraction Percentage 1/2 50% 1/3 33.33% 1/4 25% 1/5 20% 1/10 10% 1/20 5% -
Use a Calculator: For quick and accurate results, especially when dealing with complex or large numbers.
