How to Convert 0.55 to a Fraction
Converting a decimal like 0.55 to a fraction involves a few simple steps. The decimal 0.55 can be written as 55/100. This fraction can then be simplified by dividing both the numerator and denominator by their greatest common divisor (GCD).
Formula: Decimal to Fraction Conversion
For a decimal number with two decimal places (0.55), the fraction is calculated as:
Fraction = (Decimal × 100) / 100
For 0.55: (0.55 × 100) / 100 = 55/100
After converting, you can simplify the fraction by dividing both the numerator and denominator by their GCD. For 55/100, the GCD is 5, so dividing both by 5 gives the simplified fraction 11/20.
Step-by-Step Conversion
- Write the decimal as a fraction: 0.55 = 55/100
- Find the greatest common divisor (GCD): The GCD of 55 and 100 is 5.
- Divide numerator and denominator by GCD: 55 ÷ 5 = 11, 100 ÷ 5 = 20
- Simplified fraction: 11/20
Note: The simplified fraction 11/20 is equivalent to 0.55. This means that 11 parts out of 20 equal parts make up the decimal 0.55.
Simplifying the Fraction
Simplifying a fraction involves dividing both the numerator and denominator by their greatest common divisor (GCD). For 55/100:
- Factors of 55: 1, 5, 11, 55
- Factors of 100: 1, 2, 4, 5, 10, 20, 25, 50, 100
- GCD: 5
Dividing both by 5 gives the simplified fraction 11/20.
