Understanding Fractions and Decimals
Understanding the relationship between fractions and decimals is an important concept in mathematics. Fractions represent a part of a whole, and decimals represent a part of a whole in a different format. Both fractions and decimals are used to represent numbers that are not whole. In this article, we will explore how the fraction 2 and 1/2 can be expressed as a decimal.
Converting a Mixed Number to an Improper Fraction
Before converting 2 and 1/2 to a decimal, it’s important to understand how to convert a mixed number to an improper fraction. A mixed number is a combination of a whole number and a fraction. To convert a mixed number to an improper fraction, you can follow these steps:
1. Multiply the whole number by the denominator of the fraction.
2. Add the result to the numerator of the fraction.
3. Keep the denominator the same.
Using the steps above, we can convert the mixed number 2 and 1/2 to an improper fraction:
2 x 2 = 4
4 + 1 = 5
The improper fraction equivalent of 2 and 1/2 is 5/2.
Converting an Improper Fraction to a Decimal
Once we have converted the mixed number to an improper fraction, we can then proceed to convert the improper fraction 5/2 to a decimal. To convert a fraction to a decimal, you can divide the numerator by the denominator. In the case of 5/2, the division would look like this:
5 ÷ 2 = 2.5
Therefore, 2 and 1/2 as a decimal is 2.5.
