### Multiplying Decimals

Wednesday, December 2, 2009
Hey 9-05! Abby here with a blog post about multiplying decimals! Multiplying decimals may seem hard, but it's fairly easy!

So let's work with these numbers:

So first of all, you have to multiply 5 by each individual number in 13.33.

Then, you multiply 6 by each individual number in 13.33. You have to add a zero at the end because you're actually multiplying by tenths.

Next, you multiply the 7 by each individual number in 13.33. Then, add two zeros to the end.

Oh! But we're not done yet! Since each factor contains a decimal, then the product must contain a decimal too! But how do we know where to put it? All you have to do is count how many numbers there are behind the decimals.

So since there are 4 numbers behind the decimals, we change the place value of the decimal 4 place values to the left.

So 13.33 multiplied by 7.65 gives a product of.. 101.9745!
