1. What is Fraction Multiplication?

Fraction multiplication involves multiplying the numerators together and the denominators together. The product of two fractions is a new fraction where the numerator is the product of the original numerators and the denominator is the product of the original denominators.

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 (x and z) to get the new numerator, and multiplies the denominators (y and w) to get the new denominator. It then simplifies the resulting fraction if possible.

3. Importance of Fraction Multiplication

Details: Multiplying fractions is fundamental in algebra, physics, chemistry, and engineering. It's used in scaling recipes, calculating probabilities, solving proportions, and many real-world applications.

4. Using the Calculator

Tips: Enter all four values (x, y, z, w). Denominators (y and w) cannot be zero. The calculator will show the product fraction and its simplified form if simplification is 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 it.

Q3: Can I use negative numbers?
A: Yes, the calculator handles negative values. The negative sign will appear in the numerator of the result.

Q4: What about mixed numbers?
A: Convert mixed numbers to improper fractions before entering them (e.g., 2½ becomes 5/2).

Q5: Does this work with variables?
A: While the calculator uses numerical values, the same formula applies when working with algebraic fractions containing variables.
