Fractions and decimals are both numerical representations that play a crucial role in mathematics and everyday life. Understanding the relationship between these two forms is essential for proficiency in various mathematical applications. This article aims to provide a comprehensive overview of fractions and decimals, their interconversion, and their practical significance.
A fraction represents a part of a whole. It consists of two components: the numerator (top number) and the denominator (bottom number). The numerator indicates the number of equal parts being considered, while the denominator represents the total number of equal parts in the whole. For example, the fraction 2/5 represents two equal parts out of a total of five equal parts.
A decimal is a fractional number written using the decimal system. It consists of a whole number part to the left of the decimal point and a decimal part to the right. The digits to the right of the decimal point represent fractions of the place value of the digit preceding the decimal point. For example, the decimal 0.75 represents 75 hundredths, or 75/100.
To convert a fraction to a decimal, divide the numerator by the denominator. The result will be the decimal representation of the fraction.
To convert a decimal to a fraction, follow these steps:
Fractions and decimals are used extensively in various fields, including:
