1. What Is Ratio Calculation?

Ratio calculation is a mathematical operation that compares two quantities to show their relative sizes. It is expressed as A:B or A/B, representing how many times one value contains or is contained within the other.

2. How Does The Calculator Work?

The calculator uses the ratio formula:

Where:

• \( A \) — First quantity (unit)
• \( B \) — Second quantity (unit)

Explanation: The ratio is calculated by dividing value A by value B, showing the proportional relationship between the two quantities.

3. Importance Of Ratio Calculation

Details: Ratio calculation is fundamental in mathematics, science, engineering, finance, and everyday life for comparing quantities, scaling recipes, analyzing financial statements, and solving proportion problems.

4. Using The Calculator

Tips: Enter both values A and B in their respective units. Both values must be positive numbers greater than zero for accurate ratio calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a simple ratio?
A: A simple ratio expresses the relationship between two numbers in its simplest form, often reduced by dividing both terms by their greatest common divisor.

Q2: Can ratios be expressed as fractions?
A: Yes, ratios can be written as fractions (A/B) and vice versa. The ratio A:B is equivalent to the fraction A/B.

Q3: What is the difference between ratio and proportion?
A: A ratio compares two quantities, while a proportion states that two ratios are equal (e.g., A:B = C:D).

Q4: How are ratios used in real life?
A: Ratios are used in cooking (recipe scaling), finance (debt-to-income ratio), maps (scale), photography (aspect ratio), and many other practical applications.

Q5: What if one value is zero?
A: Division by zero is undefined in mathematics. Both values in a ratio must be non-zero positive numbers for meaningful calculation.
