Decimal numbers (or simply Decimals) are the fractions with 
denominators 10, 100 , 1000 etc.  
? We use a period ( or point ) called decimal point to write 
decimals. The number before the decimal point is called 
the whole part or integral part, whereas the number after 
the decimal point is called the fractional part or decimal 
part. 
? The numbers written in decimal form are called decimal 
numbers . The number of digits contained in the decimal 
part of a decimal number is known as the number of 
decimal places.
