A proportion expressed as a fraction of 100, often used to describe parts of a whole.

• A. Percentage
• B. Fraction
• C. Ratio
• D. Proportion

Answer: (A)

A percentage is a way to express a part of a whole as a fraction of 100, using the percent sign to show "per hundred." It standardizes any part of a whole to a common base of 100, making it easy to compare different quantities. For example, 25% means 25 out of 100, which is the same as the fraction 25/100 or 0.25. To convert a fraction to a percentage, multiply by 100 and add the percent symbol. The other terms describe different ideas: a fraction can be any part of a whole as a numerator over a denominator, not necessarily 100; a ratio compares two quantities; a proportion is an equation stating that two ratios are equal.
