What are Fractions?
- Fractions represent parts of a whole. They are written in the form of a/b, where a is the numerator (the number of parts) and b is the denominator (the total number of equal parts in the whole).
- Examples: 1/2 (one-half), 3/4 (three-quarters), 5/8 (five-eighths)
Types of Fractions
- Proper Fractions: The numerator is smaller than the denominator (e.g., 2/5).
- Improper Fractions: The numerator is equal to or greater than the denominator (e.g., 7/4, 5/5).
- Mixed Numbers: A combination of a whole number and a proper fraction (e.g., 2 1/3).
Fraction Calculator: Concept and Functions
What is a Fraction Calculator?
- A digital tool that performs various mathematical operations involving fractions.
- It simplifies complex calculations and provides accurate results within seconds.
Key Functions of Fraction Calculators
- Addition and Subtraction: Adds or subtracts two or more fractions with different or common denominators.
- Multiplication: Multiplies two or more fractions, simplifying the result if possible.
- Division: Divides one fraction by another, providing a simplified quotient.
- ** Simplification:** Reduces a fraction to its lowest terms by finding the greatest common factor (GCF) of the numerator and denominator.
- Conversion: Converts fractions to decimals and vice versa.
- Mixed Number Handling: Operates with mixed numbers, converting them to improper fractions or vice versa as needed.
Formulae and Key Concepts Involved
Addition and Subtraction:
- Finding a Common Denominator:
- If denominators are different, find the least common multiple (LCM) of the denominators.
- Multiply each fraction by a suitable factor to make their denominators the same.
- Adding or Subtracting Numerators:
- Once denominators are equal, add or subtract the numerators, keeping the denominator the same.
Multiplication:
- Multiply the numerators of the fractions.
- Multiply the denominators of the fractions.
- Simplify the result if possible.
Division:
- Multiply the first fraction by the reciprocal of the second fraction (flip the second fraction upside down).
- Simplify the result if possible.
Simplification:
- Find the GCF of the numerator and denominator.
- Divide both numerator and denominator by the GCF.
