-
Decimal Conversion
Following the division operation, the resulting ratio is expressed as a decimal. This decimal representation provides a standardized format for comparison and further calculation. An imprecise conversion from the fractional representation to a decimal can introduce rounding errors, which propagate through subsequent calculations. For example, truncating 10/30 to 0.3 instead of 0.333… results in a lower percentage than the actual proportion represents. Maintaining sufficient decimal places is crucial for preserving accuracy.
-
Multiplication by 100
The final step in proportional calculation entails multiplying the decimal by 100 to express the ratio as a percentage. This transformation shifts the decimal point, providing a more readily interpretable and universally understood measure.
