  1. When you divide by 10 you move 1 place to the right when you divide by 100 you move 2 places to the right.When you times by 10 you move 1 place to the left
    and when you times by 100 moves 2 places to the left.

  2. When you divide by 10 and 100 the decimal place moves to the left.Move the decimal point once according to each zero you are dividing by.When you divide by 10 and 100 the decimal place moves to the right.

  3. Multiplying:
    When you are multiplying by 10 then you move all of the digits to the left once. If you have a space left then you always add one place value holder. Whan you are multiplying by 100 thenyou move all of the digits to the left twice. If you have two spaces left then you always add two place value holders.

    Dividing:
    Whaen you are dividing by 10 then you move all of the digits one space to the right. If you end up having some of the digits in the tenths and hundreths columns then just add a point inbetween the thousonds, hundreds, tens and ones and the tenths and hundreths.

  4. Its easy i can give you some exmaples.
    1099 divided by 10 =109.9
    1099 divided by 100 =10.99
    You just increase the number with a dicabal.
    10 times by 10 =100
    10 times by 100 =1000
    You just decrease the number with a place holder.

    That how you do it.

  5. If you want to find out how to divide,then come on the journey and let’s find out
    If your dividing by ten you just move once to the right
    If your dividing by100 you move twice to the right
    Are you ready for timesing come on and goin in

    If you multiply by ten you move each place value to the left once then you add one zero at the end eg:100 multiply 10 is 1000

    If you multiply by 100 you move each place value to the left twice then you add two zeros from the 100😬😀
