Conversion Steps:
- State the given percentage: 75%.
- Calculate the remaining share: 100% - 75% = 25%.
- Write as an initial ratio: 75 : 25.
- Find Greatest Common Divisor: GCD(75, 25) = 25.
- Divide both terms by 25: 75 ÷ 25 = 3, and 25 ÷ 25 = 1.
- Simplified ratio is 3 : 1.
Understanding Percentage to Ratio Conversions
Percentages are fractions out of 100. Converting a percentage to a ratio depends on whether you are comparing the part to the remainder (part-to-part) or the part to the total (part-to-whole).
Part-to-Part: Compares the percentage to (100 - percentage). E.g. 60% → 60 : 40 → 3 : 2.
Part-to-Whole: Compares the percentage to 100. E.g. 60% → 60 : 100 → 3 : 5.
