Ratios are one of the most useful mathematical concepts for comparing two or more quantities. They are widely used in finance, business, science, statistics, cooking, construction, education, and everyday decision-making. Whether you are comparing expenses, analyzing data, adjusting recipes, or studying proportions, understanding ratios helps you see the relationship between different values.

What Is a Ratio?
A ratio is a mathematical comparison between two quantities that shows how much one value relates to another. Ratios are usually written using a colon symbol (:).
For example:
5 : 10
This means the first quantity is compared with the second quantity. The ratio indicates that for every 5 units of the first value, there are 10 units of the second value.
Ratios can also be simplified, similar to fractions.
Example:
5 : 10
Both numbers can be divided by 5:
5 ÷ 5 : 10 ÷ 5 = 1 : 2
So, the simplified ratio is:
1 : 2
Simplifying ratios makes comparisons easier to understand and communicate.
What Is a Convert To Ratio Calculator?
The Convert To Ratio Calculator is an online tool that helps users quickly convert two numbers into a simplified ratio. Instead of manually finding the greatest common divisor and performing calculations, the calculator automatically provides accurate results.
The tool provides four important outputs:
1. Simplified Ratio
The simplified ratio reduces both numbers to their smallest possible form.
Example:
Input:
- First Number: 24
- Second Number: 36
Result:
2 : 3
2. Ratio Decimal Value
The calculator also provides the decimal relationship between the two numbers.
Example:
For:
24 : 36
The decimal ratio value is:
24 ÷ 36 = 0.6667
This shows that the first value is approximately 66.67% of the second value.
3. First Number Percentage
This represents how much the first number contributes to the total amount.
Example:
Numbers:
24 and 36
Total:
24 + 36 = 60
First percentage:
24 ÷ 60 × 100 = 40%
4. Second Number Percentage
This shows the contribution of the second number.
Example:
36 ÷ 60 × 100 = 60%
Together:
40% + 60% = 100%

Ratio Formula Explained
The Convert To Ratio Calculator uses several mathematical formulas to produce accurate results.
1. Ratio Formula
The basic ratio formula is:
Ratio = First Number : Second Number
Example:
First Number = 15
Second Number = 25
Ratio:
15 : 25
2. Simplifying Ratio Formula
To simplify a ratio, divide both numbers by their greatest common divisor (GCD).
Formula:
Simplified Ratio = (First Number ÷ GCD) : (Second Number ÷ GCD)
Example:
Numbers:
18 and 24
Greatest Common Divisor:
6
Calculation:
18 ÷ 6 = 3
24 ÷ 6 = 4
Simplified Ratio:
3 : 4
3. Decimal Ratio Formula
The decimal ratio shows the relationship between the first and second numbers.
Formula:
Decimal Ratio = First Number ÷ Second Number
Example:
50 and 100
50 ÷ 100 = 0.5
Decimal Ratio:
0.5000
4. Percentage Formula
To calculate each number’s percentage contribution:
Percentage = (Individual Value ÷ Total Value) × 100
Where:
Total Value = First Number + Second Number
Example:
Numbers:
40 and 60
Total:
100
First Percentage:
(40 ÷ 100) × 100 = 40%
Second Percentage:
(60 ÷ 100) × 100 = 60%
Example Calculation Using Convert To Ratio Calculator
Suppose a company has:
- Online sales: 450 units
- Store sales: 750 units
The goal is to compare these values using a ratio.
Step 1: Create Ratio
450 : 750
Step 2: Simplify Ratio
The greatest common divisor is 150.
450 ÷ 150 = 3
750 ÷ 150 = 5
Simplified Ratio:
3 : 5
Step 3: Calculate Decimal Ratio
450 ÷ 750 = 0.6000
Step 4: Calculate Percentages
Total sales:
450 + 750 = 1200
Online sales:
450 ÷ 1200 × 100 = 37.50%
Store sales:
750 ÷ 1200 × 100 = 62.50%
Final Results:
| Calculation | Result |
|---|---|
| Simplified Ratio | 3 : 5 |
| Decimal Ratio | 0.6000 |
| First Number Percentage | 37.50% |
| Second Number Percentage | 62.50% |

| Written as A:B | Written with % symbol |
| Example: 2:3 | Example: 40% |
| Used for comparisons | Used for proportions |
Example:
A ratio of:
2 : 3
means:
- First quantity = 40%
- Second quantity = 60%
Important Tips When Using Ratios
Use Positive Numbers
Ratios normally compare quantities, so values should be greater than zero.
Keep Units Consistent
Always compare similar measurements.
Correct:
5 meters : 10 meters
Incorrect:
5 meters : 10 kilograms
Simplify Whenever Possible
A simplified ratio is easier to interpret.
Example:
100 : 200
is easier as:
1 : 2
Understand the Order
Changing the order changes the meaning.
Example:
2 : 5 is different from 5 : 2.
