You always move the decimal to the right when dividing by a number which is not a whole number. For example: In the problem 100 divided by .01, you would move the decimal two places to the right for divisor and dividend leaving you with 10000 divided by 1.
When dividing by a power of 10 (10, 100, 1000, etc.), you move the decimal to the left the same number of places as there are zeros in the divisor. For example, when dividing by 10, you move the decimal one place to the left. If the divisor is 100, you move the decimal two places to the left, and so on.
you can move it the amount of numbers you have and move it back when your done and get your decimal or you can keep it.You can move it meaning you can move it away the amout of digits yoiu have like for example ,6.78 there are 2 spaces after the decimal,when you are done multiplying you have to move it back 2 spaces or you wont get full credit.
When you are dividing.
Move the decimal place two spots to the left.
Move the decimal point one place to the right.
Dividing 80 by 3.14 is the same thing as dividing 8000 by 314. All you have to do is move the decimal point over the same number of spaces on both numbers and then divide the way you normally would.
That would signify dividing by ten.
Left.
0.018-move the decimal to places to the left
Depending on the direction, that would indicate dividing or multiplying by one hundred.
If you have a decimal, move the decimal point two places that way ---> to get percent.
When you move a decimal point to the right you are multiplying a number by 10. For example, take 3.4. If you move the decimal point to the right you get 34. This is the same as: 3.4x10 = 34. Reversing this, you are dividing by 10 by moving the decimal point to the left. For example, take 73. If you move the decimal point to the right you get 7.3. This is the same as: 73/10 = 7.3. If you move a decimal point 2 spaces to the right, you are multiplying by 100, or more generally if you move the decimal point n spaces to the right, you are multiplying by 10^n.
0.024
To divide by 100, move the decimal place 2 positions to the left. For example, 203.1 ÷ 100 = 2.031
