Fraction Operation Formula:
From: | To: |
This calculator performs combined operations of division, multiplication, and addition on three fractions. It computes (a/b) × (c/d) + (e/f) and provides the result in both fractional and decimal forms.
The calculator uses the following formula:
Where:
Explanation: The calculator first multiplies the first two fractions (a/b × c/d = (a×c)/(b×d)), then adds the third fraction by finding a common denominator (b×d×f).
Details: Understanding fraction operations is fundamental in mathematics, physics, engineering, and many real-world applications like cooking, construction, and financial calculations.
Tips: Enter all numerators and denominators as integers. Denominators cannot be zero. The calculator automatically simplifies the resulting fraction to its lowest terms.
Q1: Why does the denominator have to be positive?
A: While mathematically fractions can have negative denominators, by convention we keep denominators positive and show the sign in the numerator.
Q2: How does the calculator simplify fractions?
A: It uses the greatest common divisor (GCD) algorithm to reduce the fraction to its simplest form.
Q3: What if I get a negative result?
A: Negative results are valid and indicate the combined value is less than zero. The calculator properly handles negative signs in either numerator or denominator.
Q4: Can I enter mixed numbers?
A: This calculator requires proper fractions. Convert mixed numbers to improper fractions first (e.g., 1½ = 3/2).
Q5: What about division of fractions?
A: Division (a/b ÷ c/d) is equivalent to multiplication by the reciprocal (a/b × d/c). You can use this calculator by swapping c and d for division operations.
