1. What is a Ratio?

A ratio is a quantitative relationship between two numbers that indicates how many times the first number contains the second. It is a dimensionless number that compares two quantities of the same unit.

2. How Does the Calculator Work?

The calculator uses the ratio formula:

Where:

• \( Part1 \) — First quantity (units)
• \( Part2 \) — Second quantity (units)

Explanation: The ratio is calculated by dividing Part1 by Part2. Both parts should be in the same units for meaningful comparison.

3. Importance of Ratio Calculation

Details: Ratios are fundamental in mathematics, science, engineering, finance, and everyday life for comparing quantities, analyzing relationships, and making decisions.

4. Using the Calculator

Tips: Enter both Part1 and Part2 values in the same units. The calculator will compute their ratio, which is a dimensionless number.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between ratio and proportion?
A: A ratio compares two quantities, while a proportion states that two ratios are equal.

Q2: Can ratios be greater than 1?
A: Yes, ratios can be any positive number. A ratio greater than 1 means Part1 is larger than Part2.

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

Q4: What are some common uses of ratios?
A: Common uses include financial ratios (debt-to-equity), aspect ratios (16:9 screens), and odds ratios in probability.

Q5: What if Part2 is zero?
A: Division by zero is undefined. The calculator requires both parts to be positive numbers.
