MULTIPLICATION OF DECIMAL NUMBERS

Step.1) Convert the given decimals into like decimal.

Step.2) Multiply the decimal without decimal point by the whole number

Step.3) Place the decimal point so as to obtain as many decimal places in the product as there are in the decimal numbers   

Step.4) In the given decimal number has two decimal places, so the product of given two numbers will have 2 + 2 = 4 decimal places So, the result of that given multiplication is 

  517.6250  = 517.625      (Ans.)

Example.2) Multiply 40.2 from 5.225

Ans.) Above all given numbers if you observe those all are unlike fractions. then

40.2 = 40.200 , 5.225 = 5.225   

Step.1) Convert the given decimals into like decimal.

Step.2)  Multiply the decimal without decimal point by the whole number

Step.3)  Place the decimal point so as to obtain as many decimal places in the product as there are in the decimal numbers       

Step.4) In the given decimal number has two decimal places, so the product of given two numbers will have 3 + 3 = 6 decimal places So, the result of that given multiplication is  210.045000 = 210.045  (Ans.)
