1. What is This Calculator?

This calculator computes the product of two fractions and a decimal value. It's useful for various mathematical, scientific, and engineering calculations where multiple fractional components need to be combined.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( a \) — First numerator
• \( b \) — First denominator
• \( c \) — Second numerator
• \( d \) — Second denominator
• \( e.f \) — Decimal value

Explanation: The calculation multiplies the first fraction by the second fraction and then by the decimal value.

3. When to Use This Calculation

Details: This type of calculation is commonly used in probability, physics equations, engineering calculations, and various mathematical modeling scenarios.

4. Using the Calculator

Tips: Enter all required values. Denominators cannot be zero. The calculator will automatically handle the multiplication of fractions and decimal.

5. Frequently Asked Questions (FAQ)

Q1: What if I get a divide by zero error?
A: The calculator prevents division by zero by requiring denominators to be non-zero.

Q2: How precise is the calculation?
A: Results are calculated with floating point precision and rounded to 4 decimal places.

Q3: Can I use negative numbers?
A: Yes, the calculator accepts negative values for numerators and the decimal value.

Q4: What's the maximum value I can enter?
A: The calculator can handle very large numbers within PHP's floating point limits.

Q5: Can I chain more than two fractions?
A: This version calculates exactly two fractions and one decimal. For more complex calculations, you'd need to perform multiple operations.
