The expression of a fraction as a percentage involves converting the fraction to a decimal and then multiplying by 100. In the specific instance of eighteen thirtieths, dividing 18 by 30 yields a decimal value. This decimal, when multiplied by 100, provides the equivalent percentage.
Converting fractions to percentages is a fundamental skill in mathematics and has practical applications across various fields, including finance, statistics, and everyday problem-solving. Its importance lies in facilitating easy comparison and understanding of proportions. Historically, the use of percentages has simplified the communication of relative amounts, making it easier to grasp magnitudes and changes.
