What is the answer to 7.19×.45 plz show the work

3.2355 

Fist we line up all the numbers, we forget about the decimal for a moment and we will come back to it in the end.

   7.19
x0.45

 28760      

We put 0 first because we are working on the ten place, and we do a normal multiplication problem: 4*9= 36 (bring the 3 over). 4*1= 4+3 = 7. 4*7= 28  Then we work on the second part.  

   7.19
x0.45

 28760
   3555

As same as the first step, it is normal multiplication...

    7.19
x0.45

 28760
   3555

  32315

We all both numbers together...  For the final answer, we count the decimal place of the numbers given in the problem, 7.19 and 0.45.  They both have 2 decimal places, so 2+2=4.  So 4 decimal places.  We give the final answer 4 decimal places.
