1. What is Fraction Multiplication?

Fraction multiplication is a mathematical operation that combines two fractions to produce a new fraction. Unlike addition, fractions are multiplied by simply multiplying the numerators together and the denominators together.

2. How Does the Calculator Work?

The calculator uses the fraction multiplication formula:

Where:

• \( a \) — Numerator of first fraction
• \( b \) — Denominator of first fraction
• \( c \) — Numerator of second fraction
• \( d \) — Denominator of second fraction

Explanation: The calculator first multiplies the numerators and denominators, then simplifies the resulting fraction by finding the greatest common divisor (GCD).

3. Importance of Fraction Multiplication

Details: Fraction multiplication is fundamental in mathematics, used in scaling recipes, calculating probabilities, solving algebraic equations, and many real-world applications involving ratios and proportions.

4. Using the Calculator

Tips: Enter all four values (two numerators and two denominators). Denominators cannot be zero. The calculator will show both the fractional result (simplified if possible) and the decimal equivalent.

5. Frequently Asked Questions (FAQ)

Q1: Can I multiply more than two fractions?
A: Yes, the same rule applies - multiply all numerators together and all denominators together, then simplify.

Q2: What if one of my denominators is zero?
A: Division by zero is undefined. The calculator will not accept zero as a denominator.

Q3: How does the simplification work?
A: The calculator finds the greatest common divisor (GCD) of the numerator and denominator, then divides both by this number.

Q4: Can I enter mixed numbers?
A: This calculator requires proper fractions. Convert mixed numbers to improper fractions first (e.g., 1½ becomes 3/2).

Q5: What about negative fractions?
A: Negative signs can be placed on either numerator or denominator (but not both). The calculator handles negative values correctly.
