How to Convert 9 5th into Decimal?


Converting fractions into decimals is a fundamental skill in mathematics that is useful in various contexts. In this 1000-word blog post, we will explore the concept of converting fractions to decimals, discuss different methods for doing so, and examine the importance of this skill in everyday life, mathematics, and beyond.

How to Convert 9 5th into Decimal?

To convert the mixed number 9 5th into a decimal, first divide the whole number (9) by the denominator (5). The result is 1.8. Then, add the fractional part (0.8) to the whole number to get the decimal representation: 9 5th is equivalent to 9.8 as a decimal.

Understanding Fractions and Decimals

Fractions and decimals are two common ways to represent parts of a whole. While fractions use a numerator and a denominator to indicate the ratio of a part to a whole, decimals use a decimal point and digits to express the same concept. For example, the fraction 1/2 can be written as the decimal 0.5.

Converting Fractions to Decimals: The Basics

To convert a fraction to a decimal, you can use various methods, but one of the most common methods involves division. Here’s a step-by-step process:

Step 1: Divide the numerator by the denominator.

For example, let’s convert the fraction 3/4 into a decimal:

34÷1=3443​÷1=43​

Step 2: Perform the division.

3÷4=0.753÷4=0.75

So, 3/4 is equivalent to 0.75 when expressed as a decimal.

Method 1: Long Division

Long division is a standard method for converting fractions to decimals. It is especially useful for fractions that don’t simplify to a terminating decimal. For example, when converting 1/3 to a decimal using long division, you get the non-repeating, non-terminating decimal 0.333…

Method 2: Calculator or Software

Modern calculators and computer software have built-in functions for converting fractions to decimals. You can simply input the fraction, and the calculator or software will provide the decimal equivalent. This method is quick and accurate.

Method 3: Fraction to Decimal Conversion Chart

For common fractions like 1/2, 1/4, 1/5, and so on, there are pre-calculated decimal equivalents that can be found in conversion charts. This is a handy reference for quickly converting well-known fractions.

The Importance of Converting Fractions to Decimals
