Ratio Calculation:
| From: | To: |
Ratio calculation is a mathematical method used to compare two quantities by division. It expresses the relative size of two values and is commonly written in the form A:B or as a fraction A/B.
The calculator uses the basic ratio formula:
Where:
Explanation: The calculator also provides a simplified ratio by finding the greatest common divisor (GCD) of both parts and dividing them by this value to get the simplest whole number ratio.
Details: Ratios are fundamental in mathematics, science, engineering, finance, and everyday life. They help in comparing quantities, solving proportions, mixing solutions, financial analysis, and understanding relationships between different variables.
Tips: Enter both Part 1 and Part 2 values as positive numbers. The calculator will compute the ratio, simplified ratio, and display both input values for verification. All values must be greater than zero.
Q1: What is a ratio used for?
A: Ratios are used to compare quantities, solve proportion problems, mix ingredients in recipes, analyze financial statements, and understand scale relationships in maps and models.
Q2: How do I simplify a ratio?
A: To simplify a ratio, find the greatest common divisor (GCD) of both numbers and divide each number by the GCD to get the simplest whole number ratio.
Q3: Can ratios have units?
A: Ratios can be unitless when comparing similar quantities, or they can have units when comparing different types of quantities (e.g., miles per hour).
Q4: What is the difference between ratio and proportion?
A: A ratio compares two quantities, while a proportion states that two ratios are equal. Ratios are comparisons, proportions are equations of ratios.
Q5: How are ratios expressed?
A: Ratios can be expressed in several ways: as a fraction (3/4), with a colon (3:4), or as a decimal (0.75). All forms represent the same relationship.
