Converting fractions to decimals is a fundamental concept in mathematics that is used extensively in various real-world applications. One such conversion is turning the fraction 3/20 into its decimal form. This process involves simple arithmetic operations that can be easily understood and applied. In this article, we will delve into the steps required to convert 3/20 into a decimal, explore the concept in detail, and discuss its practical implications.
Understanding Fractions and Decimals
Before diving into the conversion of 3⁄20, it’s essential to have a basic understanding of fractions and decimals. A fraction represents a part of a whole and is expressed as a ratio of two numbers, a numerator, and a denominator. For instance, in the fraction 3⁄20, 3 is the numerator, and 20 is the denominator. On the other hand, a decimal is a way of representing fractions using a point to separate the whole number part from the fractional part.
Converting 3⁄20 to Decimal Form
To convert 3⁄20 into its decimal form, we divide the numerator (3) by the denominator (20). This operation can be performed using long division or a calculator.
3 ÷ 20 = 0.15
Therefore, the decimal form of 3⁄20 is 0.15.
