## Why is this so important?

It's important because in real life, you are going to have to multiply and divide decimals ALOT! If you are a teacher and you have to average grades, it'll be useful to know how to multiply and divide decimals if you are going to grade papers. You may not become a teacher when you grow up, bu there are much more cases where you have to multiply and divide decimals, like when you're shopping and, for example, see a shirt which is on sale for 12.97 and you buy 5, you want to know how much it is going to be before going to to the counter then realizing you don't have enough money! Here is an example...

## Line Then Up, And Don't Line a Them Up! I'm multiplying decimals, you don't want to line up the decimals, but in dividing decimals, you want to line the decimals up. | ## Dividing Decimals! When you divide decimals, you do the same process of regular long division, but there is something else now. When you bring down the first number to the right of the decimal, known as the tenths, you put a decimal in your answer. On the left, there is a diagram for more info! | ## Multiplying decimals! Just like dividing decimals, you do the multiplication process the same way you would normally do it. But, when you think you have your final answer, after all the multiplying, you actually don't have a FINAL answer. You need to count ALL of the numbers to THE RIGHT OF THE DECIMAL! Then count the spaces, starting from the left, and once you have counted all the spaces that you needed to, put your decimal in front of the last space that you counted. |
