1. What is Fraction Multiplication?

Fraction multiplication is a mathematical operation that combines two fractions to produce a new fraction. The numerator of the product is the product of the numerators, and the denominator is the product of the denominators.

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 together and denominators together, then simplifies the resulting fraction by dividing both numerator and denominator by their greatest common divisor.

3. Importance of Fraction Multiplication

Details: Multiplying fractions is fundamental in mathematics, used in scaling recipes, calculating probabilities, determining areas, and solving many real-world problems involving ratios and proportions.

4. Using the Calculator

Tips: Enter integers for all four values (two numerators and two denominators). Denominators cannot be zero. The calculator will show both the raw product and simplified form (if simplification is possible).

5. Frequently Asked Questions (FAQ)

Q1: Can I multiply mixed numbers with this calculator?
A: First convert mixed numbers to improper fractions (e.g., 2½ becomes 5/2), then use the calculator.

Q2: What if one denominator is zero?
A: Division by zero is undefined. The calculator requires non-zero denominators.

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

Q4: Can I multiply more than two fractions?
A: Yes, multiply the first two, then multiply the result with the next fraction, and so on.

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