UNIT 15: DECIMAL MULTIPLICATION

To multiply 2 decimals, you merely multiply the 2 numbers together, ignoring the decimal points. Then, when you have your answer (called the "product"), you add the number of digits to the right of the decimal point in each number together and place the decimal in your answer (product) that many places from the RIGHT.
YOU DON'T LINE UP THE DECIMAL POINTS!

EXAMPLES:






Here's another way to figure out where to put the decimal:

Get rid of everything to the right of the decimal (in your head) in both numbers, and multiply the numbers together. In our second example this becomes 3 x 2 = 6.
Now place the decimal in the original product to make it closest to 6. In this case, right after the 7!

Multiply these decimals:

You don't have to
line up the decimals
to multiply!
