Determining the percentage equivalent of a fraction involves converting the fraction into a decimal and then multiplying by 100. In the specific instance of twenty twenty-fifths, dividing 20 by 25 yields 0.8. Multiplying 0.8 by 100 results in 80, thus representing 80 percent.
Expressing fractions as percentages facilitates easier comparison and understanding of proportions. This conversion finds application across various fields, including finance, statistics, and everyday calculations, allowing for quick interpretation and effective communication of relative values. The historical roots of percentage calculations can be traced back to ancient Rome, where taxes were often calculated as a fraction of assets. This concept has since evolved into a standardized method for representing proportions.
