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.

Now, what you have to do is add the answers up.

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!


So that's my post about multiplying decimals! I hope I explained this well! If there are any errors, or you don't understand anything, please feel free to comment! Thanks for reading guys! Have a good evening 9-05!
