In mathematics, fractions are a way to represent numbers that are not whole numbers. They are used to express parts of a whole or a ratio between two quantities. One common fraction is 1/5, which represents one part out of five equal parts.
To find the decimal representation of 1/5, we divide the numerator (1) by the denominator (5). The answer is 0.2.
There are multiple methods to solve 1/5 as a decimal. Let's explore two common approaches:
To solve 1/5 as a decimal using long division, follow these steps:
Another method to solve 1/5 as a decimal is by converting the denominator to 1000. Here are the steps:
Let's explore a few more examples to solidify our understanding:
Example: 3/5 as a Decimal
Example: 7/5 as a Decimal
Example: 2/5 as a Decimal
In mathematics, fractions represent parts of a whole or a ratio between two quantities. They consist of a numerator and a denominator, separated by a slash (/). Fractions can be proper (numerator < denominator), improper (numerator > denominator), or mixed numbers (a whole number combined with a fraction).
The most common symbol used to represent fractions is the slash (/). For example, 1/5 represents one-fifth. Additionally, fractions can be represented using a horizontal line, such as 1 over 5.
There are several types of fractions, including:
A fraction consists of two components:
Decimals are another way to represent numbers in mathematics. They are based on powers of 10 and are used to express numbers that are not whole numbers. Decimals can represent both fractions and rational numbers.
The symbol used to represent decimals is a dot or a period (.), placed between the whole number part and the fractional part. For example, 0.2 represents two-tenths.
Decimals consist of two components:
There are several types of decimals, including:
In conclusion, 1/5 as a decimal is 0.2. We can solve this by using methods like long division or converting the denominator to 1000. Fractions represent parts of a whole or a ratio between two quantities, and they are represented using symbols like the slash (/). Decimals, on the other hand, are another way to represent numbers and are denoted by a dot or period (.). They can be classified into different types based on their properties.
