Question 498522: 3.2*12.8
Answer by Flannery(124)   (Show Source):
You can put this solution on YOUR website! The rule here is to stack the decimals up
12.8
03.2
multiply in the usual way
count the total number of digits to the right of all your decimal points
and insert the decimal point into the answer THAT many places to the left
of your rightmost digit
32 times 128 is 4096
so 3.2 times 12.8 is 40.96
