Understanding Fractions and Percentages
Before we dive into the conversion process, let’s clarify what fractions and percentages represent.
-
Fraction: A fraction consists of two numbers separated by a slash: a numerator (top number) and a denominator (bottom number). For example, in ( \frac{3}{9} ), 3 is the numerator and 9 is the denominator.
-
Percentage: A percentage is a way of expressing a number as a fraction of 100. For example, 50% means 50 out of 100.
Thus, to convert a fraction to a percentage, you need to express the fraction in terms of 100.
Step-by-Step Conversion Process
Step 1: Simplify the Fraction
The first step in converting ( \frac{3}{9} ) to a percentage is to simplify the fraction if possible.
To simplify a fraction, divide the numerator and the denominator by their greatest common divisor (GCD). The GCD of 3 and 9 is 3.
So, we can simplify ( \frac{3}{9} ) as follows:
[ \frac{3 \div 3}{9 \div 3} = \frac{1}{3} ]
Step 2: Convert to Decimal
Next, convert the simplified fraction ( \frac{1}{3} ) into a decimal by dividing the numerator by the denominator.
[ 1 \div 3 = 0.3333 , (\text{repeating}) ]
Step 3: Convert to Percentage
To convert a decimal to a percentage, multiply it by 100.
[ 0.3333 \times 100 = 33.33% ]
Thus, ( \frac{3}{9} ) as a percentage is 33.33%! 🎉
