1. What is Fraction Multiplication?

Fraction multiplication is a mathematical operation where two fractions are multiplied by multiplying their numerators together and their denominators together. The result is a new fraction that represents the product of the original fractions.

2. How Does the Calculator Work?

The calculator uses the fraction multiplication formula:

Where:

• \( x \) — Numerator of first fraction
• \( y \) — Denominator of first fraction
• \( z \) — Numerator of second fraction
• \( w \) — Denominator of second fraction

Explanation: The calculator multiplies the numerators together and denominators together, then simplifies the resulting fraction if possible.

3. Importance of Fraction Multiplication

Details: Multiplying fractions is fundamental in algebra, physics, chemistry, and engineering calculations. It's essential for solving equations, scaling recipes, calculating probabilities, and more.

4. Using the Calculator

Tips: Enter all four values (two numerators and two denominators). Denominators cannot be zero. The calculator will show the product in both unsimplified and simplified forms when possible.

5. Frequently Asked Questions (FAQ)

Q1: What if one of the denominators is zero?
A: Division by zero is undefined. The calculator requires non-zero denominators.

Q2: How does the simplification work?
A: The calculator finds the greatest common divisor (GCD) of the numerator and denominator and divides both by this number.

Q3: Can I use negative numbers?
A: Yes, the calculator handles negative numbers. A negative denominator will make the whole fraction negative.

Q4: Does this work with variables?
A: While this calculator uses numerical values, the same principle applies when working with algebraic fractions containing variables.

Q5: What about mixed numbers?
A: Convert mixed numbers to improper fractions first (e.g., 2½ becomes 5/2).
