To multiply
decimal numbers:
- Multiply
the numbers just as if they were whole numbers.
- Line up the
numbers on the right - do not align the decimal points.
- Starting
on the right, multiply each digit in the top number by each digit in the
bottom number, just as with whole numbers.
- Add the
products.
-
Place the decimal point in the answer by starting at the right and moving
a number of places equal to the sum of the decimal places in both numbers
multiplied.
