What is Percent to Ratio Conversion?
Converting percentages to ratios expresses the same proportion in a different format. Ratios are often more practical for mixing, comparing quantities, and understanding proportional relationships.
How to Convert Percent to Ratio
The conversion formula is:
[\text{Ratio} = \frac{\text{Percentage}}{100} : 1]
Conversion Examples
| Percentage | Ratio |
|---|---|
| 10% | 0.10:1 |
| 25% | 0.25:1 |
| 50% | 0.50:1 |
| 75% | 0.75:1 |
| 100% | 1.00:1 |
| 200% | 2.00:1 |
Practical Example
If a cleaning solution requires 20% concentrate:
[\text{Ratio} = \frac{20}{100} = 0.2:1]
This means 0.2 parts concentrate to 1 part water, or equivalently, 1 part concentrate to 5 parts water.
