*Decimals:** *

*The numbers written in the decimal form are called decimal numbers or simply decimals*

*Ex: *

*4.1 is read four point one*

*12.05 is read twelve point zero five.*

*The decimal number(decimal) has two parts *

*whole number part and decimal part*

*These parts are separated by a dot(**.** **)** called decimal point*

*The parts to the right of the decimal point is called the decimal part of the number * *and the part to the left of the decimal point is called the integral part (whole number)*

*The digits in decimal part are read individually (including zero) with out naming the places.*

*The decimal part of the number is always less than one.*

*If there is no number in whole number part, it should be taken as zero ‘0’ *

*For example .7 can written as 0.7in 0.4 there is one decimal place.*

*Addition of decimals:*

*Step 1 : **Convert all the given decimals into like decimals*

*Step 2 :** **Write the decimals one under the other with decimal points of all the addends in the same column*

*Step 3 :** **Add as in the case of whole number.*

*Step 4 :** **In the sum, put the decimal point directly under the decimal points of the addends.*
