Understanding the Basics of Fractions and Decimals

In mathematics, fractions and decimals are two ways to represent a part of a whole. A fraction is a way to express a part of a whole as a ratio of two numbers, while a decimal is a way to express a part of a whole as a number with a point separating the whole number part from the fractional part. In this article, we will focus on converting fractions to decimals, specifically by creating an equivalent fraction with a denominator of 100.

Why Convert Fractions to Decimals?

Converting fractions to decimals is an essential skill in mathematics, as it allows us to perform various operations, such as addition, subtraction, multiplication, and division, with ease. Decimals are also more intuitive and easier to work with in many real-world applications, such as finance, science, and engineering. By converting fractions to decimals, we can make calculations more efficient and accurate.

Creating an Equivalent Fraction with a Denominator of 100

To convert a fraction to a decimal, we need to create an equivalent fraction with a denominator of 100. This can be done by multiplying both the numerator and the denominator of the original fraction by a number that will result in a denominator of 100. For example, let's consider the fraction 520\frac{5}{20}.

Step 1: Identify the Denominator

The denominator of the fraction 520\frac{5}{20} is 20.

Step 2: Determine the Multiplication Factor

To create an equivalent fraction with a denominator of 100, we need to multiply the denominator by a factor that will result in 100. In this case, we can multiply the denominator by 5, since 20×5=10020 \times 5 = 100.

Step 3: Multiply the Numerator

Now that we have determined the multiplication factor, we need to multiply the numerator by the same factor. In this case, we multiply the numerator 5 by 5, resulting in 25.

Step 4: Write the Equivalent Fraction

The equivalent fraction with a denominator of 100 is 25100\frac{25}{100}.

Converting the Equivalent Fraction to a Decimal

Now that we have created an equivalent fraction with a denominator of 100, we can convert it to a decimal by dividing the numerator by the denominator.

Step 1: Divide the Numerator by the Denominator

To convert the equivalent fraction 25100\frac{25}{100} to a decimal, we divide the numerator 25 by the denominator 100.

Step 2: Simplify the Result

The result of the division is 0.25.

Conclusion

Converting fractions to decimals is an essential skill in mathematics, as it allows us to perform various operations with ease. By creating an equivalent fraction with a denominator of 100, we can convert fractions to decimals and make calculations more efficient and accurate. In this article, we have walked through the steps of converting the fraction 520\frac{5}{20} to a decimal by creating an equivalent fraction with a denominator of 100.
