Understanding Fractions
Before diving into formulas, it’s important to understand what a fraction is.
A fraction consists of two parts:
- Numerator – the top number
- Denominator – the bottom number
Example:
👉 3/4
- 3 = numerator
- 4 = denominator
Conversion Formulas Explained
This calculator uses different formulas depending on the selected conversion type.
1. Fraction to Decimal Formula
To convert a fraction into a decimal:
Decimal = Numerator ÷ Denominator
This is simply division.
2. Fraction to Percentage Formula
To convert a fraction into a percentage:
Percentage = (Numerator ÷ Denominator) × 100
The result is expressed with a percent (%) sign.
3. Simplifying a Fraction
To simplify a fraction, we divide both numerator and denominator by their Greatest Common Divisor (GCD).
Simplified Fraction = (Numerator ÷ GCD) / (Denominator ÷ GCD)
What Is GCD (Greatest Common Divisor)?
The GCD is the largest number that divides both numerator and denominator without leaving a remainder.
Example:
For 8 and 12:
- Factors of 8: 1, 2, 4, 8
- Factors of 12: 1, 2, 3, 4, 6, 12
👉 GCD = 4
Practical Examples
Let’s understand how the calculator works with real examples.
Example 1: Convert Fraction to Decimal
Fraction: 5/8
Decimal = 5 ÷ 8 = 0.625
Example 2: Convert Fraction to Percentage
Fraction: 3/5
Percentage = (3 ÷ 5) × 100
= 0.6 × 100
= 60%
Example 3: Simplify a Fraction
Fraction: 12/18
GCD of 12 and 18 = 6
Simplified form:
12 ÷ 6 = 2
18 ÷ 6 = 3
👉 Result = 2/3
Common Fraction Conversions Table
| Fraction | Decimal | Percentage |
|---|---|---|
| 1/2 | 0.5 | 50% |
| 1/4 | 0.25 | 25% |
| 3/4 | 0.75 | 75% |
| 1/5 | 0.2 | 20% |
| 2/3 | 0.6667 | 66.67% |
