Understanding the Basics of Fractions and Percentages
What is a Fraction?
A fraction represents a part of a whole. It is expressed as a quotient, with a numerator (the top number) and a denominator (the bottom number). For example, in the fraction 3/4, 3 is the numerator, and 4 is the denominator.
What is a Percentage?
A percentage is simply a fraction out of 100. It is denoted by the symbol “%”. For instance, 45% indicates 45 out of 100. When we convert fractions to percentages, our goal is to express the fraction in a way that compares it to 100.
The Conversion Process: Step-by-Step Guide
Method 1: Simple Division and Multiplication
-
Divide the Numerator by the Denominator: For the fraction ( \frac{3}{4} ): [ 3 \div 4 = 0.75 ]
-
Multiply the Result by 100: [ 0.75 \times 100 = 75% ]
Method 2: Cross-Multiplication
You can also use cross-multiplication, especially when you want to compare fractions to 100:
-
Set the fraction equal to a percentage. [ \frac{3}{4} = \frac{x}{100} ]
-
Cross-multiply: [ 3 \times 100 = 4 \times x ] [ 300 = 4x ]
-
Solve for ( x ): [ x = \frac{300}{4} = 75 ]
Thus, ( \frac{3}{4} = 75% ). 🎉
Conversion Examples
To further clarify the process, let’s look at some additional examples.
| Fraction | Decimal | Percentage |
|---|---|---|
| ( \frac{1}{2} ) | 0.5 | 50% |
| ( \frac{1}{4} ) | 0.25 | 25% |
| ( \frac{3}{5} ) | 0.6 | 60% |
| ( \frac{7}{10} ) | 0.7 | 70% |
Important Note:
"Always remember to simplify the fraction to its lowest terms before converting for accuracy. This makes calculations easier."
