1. What is a Ratio?

A ratio is a quantitative relationship between two numbers showing how many times one value contains or is contained within the other. Ratios are unitless and widely used in mathematics, science, engineering, and everyday comparisons.

2. How Does the Calculator Work?

The calculator uses the simple ratio formula:

Where:

• \( a \) — Numerator (first value)
• \( b \) — Denominator (second value)
• \( r \) — Resulting ratio (unitless)

Explanation: The ratio represents how many times the numerator contains the denominator. For example, a ratio of 2 means the numerator is twice as large as the denominator.

3. Importance of Ratio Calculation

Details: Ratios are fundamental in comparing quantities, analyzing proportions, mixing solutions, financial analysis, and many scientific calculations. They provide a normalized way to compare different quantities.

4. Using the Calculator

Tips: Enter any positive numbers for numerator and denominator. The denominator must be greater than zero. Results are rounded to 4 decimal places.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between ratio and fraction?
A: Mathematically they're similar, but ratios typically compare two different quantities, while fractions represent parts of a whole.

Q2: Can ratios be greater than 1?
A: Yes, when the numerator is larger than the denominator. Ratios can range from 0 to infinity.

Q3: How are ratios expressed?
A: Ratios can be written as fractions (3/4), with a colon (3:4), or as a decimal (0.75).

Q4: What does a ratio of 1 mean?
A: A ratio of 1 means the two quantities are equal in value.

Q5: Can I compare ratios directly?
A: Yes, ratios can be compared directly since they're normalized values. A ratio of 2 is twice as large as a ratio of 1.
