These three concepts are different ways of representing the same value, making it easier to work with numbers in various contexts. Let's start by defining each term and then explore how they connect. Fractions represent a part of a whole and consist of two parts: the numerator (the top number) and the denominator (the bottom number). The fraction 1/20, for example, means one part out of twenty. Understanding fractions is the first step toward grasping more complex mathematical concepts. They are commonly used in everyday life, from cooking recipes to dividing resources. Decimals are another way to represent parts of a whole, using a base-10 system. They use a decimal point to separate the whole number from the fractional part. For instance, 0.05 is a decimal representation. Decimals provide a more precise way of expressing fractions, particularly when dealing with measurements and financial calculations. They make it simpler to perform arithmetic operations and are widely used in scientific and engineering fields. Percentages, on the other hand, are a way of expressing a number as a fraction of 100. The term “percent” means “per hundred,” and the symbol “%” is used to denote percentages. For instance, 5% means 5 out of 100. Percentages are exceptionally useful for comparing proportions and understanding changes in values. They are prevalent in business, finance, and statistics, aiding in clear communication and decision-making. The key to mastering these concepts is recognizing their interconnectedness. Fractions can be converted to decimals, and decimals can be converted to percentages, and vice versa. This flexibility allows us to choose the most convenient representation for a particular situation, enhancing our ability to solve problems effectively. This foundational knowledge sets the stage for our exploration of converting 1/20 to a percentage. Understanding these relationships not only simplifies mathematical calculations but also sharpens our analytical skills in practical contexts.

Alternative Method: Converting to Decimal First

While the direct method of converting a fraction to a percentage is effective, another approach involves converting the fraction to a decimal first and then to a percentage. This method can be particularly useful when dealing with fractions that don’t easily convert to a denominator of 100. Understanding this alternative method enhances your flexibility in handling various mathematical conversions. Let's break down the steps involved in this process. Step 1: Convert the Fraction to a Decimal - Divide the numerator (1) by the denominator (20) to convert the fraction 1/20 to a decimal. This step provides a decimal representation of the fraction, which is a necessary intermediate form. Performing the division, 1 ÷ 20 = 0.05. This decimal value represents the same proportion as the original fraction, but in a different format. Step 2: Convert the Decimal to a Percentage - Multiply the decimal by 100 to convert it to a percentage. This step shifts the decimal point two places to the right, effectively expressing the number as a part of 100. Multiplying by 100 is the standard procedure for converting decimals to percentages, making the process straightforward and consistent. So, 0.05 * 100 = 5%. Therefore, the decimal 0.05 is equivalent to 5%. This method provides an alternative way to arrive at the same percentage, offering a different perspective on the conversion process. Using this method can be especially beneficial when working with fractions that are not easily converted to having a denominator of 100. It also reinforces the relationship between fractions, decimals, and percentages, solidifying your understanding of these fundamental mathematical concepts. By mastering both methods, you’ll be well-equipped to handle a variety of conversion problems, increasing your confidence and proficiency in mathematical calculations.
