Sal shows that when there is a decimal divisor, you need to shift the decimal first and then divide. Created by Sal Khan and Monterey Institute for Technology and Education.

• If I have a remainder how do I get rid of it? Someone told me you can do that.
• you cant really get rid of it. just add a zero to the end of the number in the division box thing. continue the prob. until you get an awnswer without a remainder.
• why move the decimal?
• to make it a whole number

• What do you do with a remainder when dividing decimals?
• The video is only for me, but you just turn it into a fraction, decimal, or remainder,
• Can you take the decimal out of the number, divide and put it back. I'm pretty sure it's not correct. So, if you multiply the decimal as much as you need to, you get a whole number and not to change the value you do the same two the number your dividing into. Is the correct? Are their other methods?
• If I'm reading your question right, then yeah you're right! The trick would be to know where to place your decimal point when you have your answer.

Another method to dividing would be to divide by the whole number first.
For example: 10.925/2.5
First you should find how many times 2.5 can go into 10, which is 4.
After that you have 0.925 left to divide, but 2.5 isn't gonna fit in 0.925 so the decimal point has to go after the 4.
Now you can use your other method to find how many times 25 goes into 925 which is 37.
• Is there a video for dividing a whole number from a fraction?
• why at do you multiply if you get the same answer?

• Decimals are everywhere - Think about how many places in life you use money. Monetary transactions all use decimals. If you want to be able to manage your money, then you need to understand decimals.
