Fraction Subtraction Formula:
From: | To: |
Fraction subtraction involves finding the difference between two fractions. To subtract fractions, they must have a common denominator, which is achieved by finding the least common multiple of the denominators or simply multiplying the denominators together.
The calculator uses the fraction subtraction formula:
Where:
Explanation: The calculator first finds a common denominator by multiplying the denominators, then subtracts the adjusted numerators, and finally simplifies the result if possible.
Details: Mastering fraction subtraction is essential for algebra, measurements, ratios, and real-world applications like cooking, construction, and financial calculations.
Tips: Enter numerators and denominators as integers. Denominators must be positive numbers. The calculator will show the result in both unsimplified and simplified forms when possible.
Q1: Can I subtract fractions with different denominators?
A: Yes, this calculator automatically finds a common denominator by multiplying the denominators together.
Q2: What if my result is an improper fraction?
A: The calculator will display the improper fraction and its simplified form. You can convert it to a mixed number if needed.
Q3: How does the simplification work?
A: The calculator uses the greatest common divisor (GCD) to reduce the fraction to its simplest form.
Q4: What if I enter negative numbers?
A: Negative numerators are allowed and will be handled correctly. Denominators must remain positive.
Q5: Can I use this for mixed numbers?
A: First convert mixed numbers to improper fractions, then use the calculator.
