1. What Is The Regel Van 3?

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

2. How Does The Calculator Work?

The calculator uses the Rule of Three equation:

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 Proportional Calculation

Details: Proportional calculations are fundamental in mathematics, finance, cooking, construction, and many everyday situations where relationships between quantities need to be maintained.

4. Using The Calculator

Tips: Enter three known values (a, b, and c). All values must be positive numbers (a and b must be greater than 0). The result x will be calculated and displayed with the same unit as value c.

5. Frequently Asked Questions (FAQ)

Q1: What if value a is zero?
A: Value a cannot be zero as division by zero is mathematically undefined. Please enter a positive value for a.

Q2: Can this be used for different units?
A: Yes, as long as the units are consistent. The result x will have the same unit as value c.

Q3: What types of problems can this solve?
A: This can solve various proportionality problems including scaling recipes, calculating dosages, determining prices, and converting measurements.

Q4: Are negative values allowed?
A: No, this calculator only accepts positive values as it's designed for real-world proportional calculations.

Q5: How precise are the results?
A: Results are calculated with high precision (4 decimal places) to ensure accuracy in various applications.
