1. What is a Ratio?

A ratio is a quantitative relationship between two numbers showing how many times the first number contains the second. Ratios are used to compare quantities in mathematics, science, engineering, and everyday life.

2. How Does the Calculator Work?

The calculator uses the simple ratio equation:

Where:

• \( Number1 \) — The numerator (first number)
• \( Number2 \) — The denominator (second number)

Explanation: The ratio is calculated by dividing the first number by the second number. The result shows how many times one number contains the other.

3. Importance of Ratio Calculation

Details: Ratios are fundamental in comparing quantities, analyzing proportions, and making decisions based on relative sizes. They are used in finance, science, cooking, and many other fields.

4. Using the Calculator

Tips: Enter both numbers (numerator and denominator). The denominator cannot be zero. The result will be displayed as a unitless ratio.

5. Frequently Asked Questions (FAQ)

Q1: What if the denominator is zero?
A: Division by zero is undefined. The calculator will not display a result if zero is entered as the denominator.

Q2: What are common uses of ratios?
A: Ratios are used in financial analysis (debt-to-equity), cooking (ingredient proportions), maps (scale), and science (stoichiometry).

Q3: How is ratio different from percentage?
A: A ratio compares two quantities directly, while a percentage expresses a ratio as a fraction of 100.

Q4: Can ratios be simplified?
A: Yes, ratios can often be simplified by dividing both numbers by their greatest common divisor.

Q5: What does a ratio of 1:1 mean?
A: A 1:1 ratio means the two quantities are equal in value or amount.
