1. What is the Regula 3 Simpla?

Regula 3 Simpla (Simple Rule of Three) is a mathematical method for solving proportionality problems. It's used to find an unknown value when three other values are known and in proportion.

2. How Does the Calculator Work?

The calculator uses the simple rule of three formula:

Where:

• \( a \) — First known value (unitless)
• \( b \) — Second known value (unitless)
• \( c \) — Third known value (unitless)
• \( x \) — Unknown value to calculate (same unit as c)

Explanation: This formula calculates the proportional relationship between four values where a is to b as c is to x.

3. Importance of Rule of 3 Calculation

Details: The rule of three is fundamental in mathematics and has practical applications in everyday life, including cooking, construction, finance, and many other fields where proportional relationships exist.

4. Using the Calculator

Tips: Enter all three known values (a, b, and c). All values must be positive numbers, and a cannot be zero as division by zero is undefined.

5. Frequently Asked Questions (FAQ)

Q1: When should I use the rule of three?
A: Use it when you have a proportional relationship between four values and need to find one unknown value.

Q2: What are some practical applications?
A: Scaling recipes, calculating discounts, converting units, determining travel time, and many other proportional calculations.

Q3: Can this be used with different units?
A: Yes, but all values must use consistent units for accurate results.

Q4: What if a equals zero?
A: Division by zero is mathematically undefined, so a must be a positive number greater than zero.

Q5: How accurate are the results?
A: The results are mathematically precise for the given inputs, following the proportional relationship exactly.
