4.2 Multiply Decimals (p.80-83)

I. Multiply as if you were multiplying whole numbers (pretend there is no decimal while mulitplying)
II. Count the number of decimal places in the factors (the numbers you multiplied together)
III. Starting at the right of your answer, count over that number of spaces. That is where the decimal point will be placed.

Ex.
0.14 two spaces
x 7 zero space
----
0.98

Here's a link from Harcourt that explains how to multiply decimals.
