First, remove the decimal points. We come back to this later.







Now we have to put in the decimal point. Count the number of digits after the decimal point for each of the two numbers: 63.55 has 2 and 7.11 also has 2, 2+2=4 so we need to put the decimal point 4 places from the end of the product: 451.8405.
