Understanding the Basics: What Are Fractions And Decimals?

Fractions:

  • A fraction is a mathematical expression that represents a part of a whole. It consists of two numbers, one written above the other and separated by a horizontal line. 

  • The number above the line is called the numerator, and the number below the line is called the denominator. The fraction a/b​ represents a parts out of a whole divided into ‘b equal parts. For example, 3/4 represents three parts out of four.

Decimals:

Decimals are another way to express numbers. They are a system of representing numbers based on powers of 10. A decimal number can include a whole number part, a decimal point, and a fractional part. For example, in the decimal 2.752.75, “2” is the whole number part, and “.75” is the decimal part.

Converting Between Fractions and Decimals:

Converting between fractions and decimals involves expressing the same quantity in different forms. This conversion is essential for several reasons:

Ease of Calculation:

  • Decimal numbers are often easier to work with in calculations, especially in arithmetic operations like addition, subtraction, multiplication, and division.

Comparisons:

Step-by-Step Guide: Converting Fractions to Decimals:

Numerator:

The numerator is the top number in a fraction. It represents the number of parts you have out of the whole. For example, in the fraction 3443​, 3 is the numerator. It indicates that you have 3 parts of the whole.

Denominator:

The bottom number in a fraction is the denominator. It represents the total number of equal parts into which the whole is divided. In the fraction 3443​, 4 is the denominator. It signifies that the whole is divided into 4 equal parts.

Decimal:

A decimal is a way of expressing numbers that are not whole. It includes a decimal point, separating the entire number from the fractional part. For example, in the decimal 2.752.75, 2 is the fundamental number part, and .75 is the decimal part.

Now, let’s go through the step-by-step guide to converting fractions to decimals:

How to Convert Fractions to Decimals

Step 1: Understand the Fraction

  • Examine the given fraction. Spot the numerator (top number) and the denominator (bottom number).

Step 2: Divide the Numerator by the Denominator

  • Divide the numerator by the denominator. It is the key step in converting a fraction to a decimal.

Step 3: Perform the Division

  • Perform the division. You have your answer if the division results in a terminating decimal (one that ends). If it is a repeating decimal, continue the division until the pattern repeats or use the appropriate notation for repeating decimals.

Example: Convert 3/4​ to a Decimal

Step 1: Understand the Fraction

  • 3/4​ has a numerator (3) and a denominator (4).

Step 2: Divide the Numerator by the Denominator

  • =3÷4.

Step 3: Perform the Division

  • 3÷4=0.753÷4=0.75. Since this is a terminating decimal, we stop here.
