Fractions and decimals are two different ways of representing numbers that are not whole numbers. A fraction is a number that represents a part of a whole. It consists of two numbers separated by a line: the numerator and the denominator. The numerator is the top number, representing the part of the whole, and the denominator is the bottom number, representing the total number of parts in the whole. For example, 3/4 represents three parts out of four equal parts in a whole.  
On the other hand, a decimal is a number that represents a fraction of a whole using a base-ten system. It consists of a whole number and a decimal point, followed by one or more decimal places. The decimal point separates the whole number from the decimal part. For example, 0.75 represents the same value as 3/4.  
To convert a fraction to a decimal, you need to divide the numerator by the denominator. For example, to convert 3/4 to a decimal, divide 3 by 4, which gives you 0.75. You can also use a calculator to convert fractions to decimals. To do this, enter the numerator, then divide it by the denominator using the division button on your calculator.  
It's important to understand fractions and decimals because they are used in many different areas of life, including math, science, and finance. For example, decimals are used in money calculations, where you need to calculate percentages, interest rates, and exchange rates. Fractions are used in cooking, where you need to measure ingredients accurately, and in construction, where you need to measure distances and angles precisely.  
In summary, fractions and decimals are two different ways of representing numbers that are not whole numbers. To convert a fraction to a decimal, you need to divide the numerator by the denominator. Understanding fractions and decimals is essential for many different areas of life.Types of Calculators
