Our **Ratio Calculator** is a user-friendly online tool designed to simplify and calculate the proportions between two or more numbers. This calculator is invaluable for students, educators, financial analysts, and anyone involved in planning or resource allocation where understanding ratios is crucial.

To use the calculator, enter the values of the items you want to compare in the ratio fields. Our tool will then compute and present the ratio in its simplest form, alongside the decimal equivalent for one part of the ratio to the other.

For instance, entering a ratio of 10:19 will result in 1:1.9, simplifying the given ratio and also providing a decimal conversion of \(0.5263157894736842:1\).

**How to calculate a ratio?**Divide each part by the greatest common divisor (GCD) of all parts to simplify the ratio to its smallest whole number form.**What is the ratio of 3 to 5?**The ratio of 3 to 5, written as 3:5, indicates that for every 3 units of the first quantity, there are 5 units of the second quantity.**What is the ratio of 5 to 1?**A 5 to 1 ratio (5:1) means that there are 5 parts of the first quantity for every single part of the second quantity.**How do you calculate the proportions?**Proportions are calculated by setting two ratios equal to each other and solving for the unknown quantity, often involving cross-multiplication.**What is a 10 to 1 ratio?**A 10 to 1 ratio (10:1) indicates that for every 10 units of the first quantity, there is 1 unit of the second quantity.**What is a 1 to 2 ratio?**A 1 to 2 ratio (1:2) signifies that for every unit of the first quantity, there are two units of the second quantity.**Which ratio is greater?**To determine which ratio is greater, convert them to decimals or simplify them for a direct comparison.**What is a unit rate?**A unit rate is a ratio that compares a quantity to one unit of another quantity, typically simplified to show the amount per one unit of the denominator.**How do you simplify ratios?**Simplify ratios by dividing all parts of the ratio by their greatest common divisor (GCD), resulting in the smallest whole numbers that maintain the same proportion.
