When dividing decimals the divisor must always be a?
The divisor must always be a whole number. If it is not already, then you must multiply both the the divisor and dividend by ten until the divisor is no longer a decimal. For example, let's say you have to divide 1.0/0.5 . The divisor in this case would be 0.5 . To multiply by ten, simply move the decimal over to the right one space. That would leave you with 5.0, but since you have to do it on both sides, the final expression would look like this: 10/5 .

Eliminate it as for example 25.5 divided by 8.5 is the same as 255 divided by 85 which is 3 in both divisions
Must a decimal divisor and a decimal dividend have the same number of decimal places?
No.
Why do you move the decimal to divide a decimal by a decimal?
To move the decimal you must move the decimal in the divisor all the way to the right to make it a whole number. Then in the dividend, you move that decimal to the right the same amount of spaces you did in the divisor.

How is dividing a decimal by a whole number different than dividing 2 decimals?
Unlike dividing by a whole number, dividing buy a decimal number cannot be done directly - the divisor must first be converted to a whole number (and then the division can be done). The easiest way to do this conversion is to keep multiplying the divisor by 10 until a whole number is obtained; however, whatever is done to the divisor must also be done to the dividend, so by whatever the divisor is multiplied, the dividend must also be multiplied.

How is dividing decimals similar to dividing whole numbers?
In that you carry out exactly the same steps - AND you must determine the correct position of the decimal point.

How do you write 0.00006 as a fraction?
3/50000(simplified) or 6/100000, an easy way to figure out decimals like this is dividing by 10 moves the decimal point back by 1. So starting at 6, the decimal must move 5 places, so dividing 6 by 100000 (6/100000) will make 0.00006. If you must move the decimal forward do the opposite and multiply.
When adding or subtracting decimals the decimal point must be in line for all numbers?
Yes.

How do you know what power of 10 to multiply a divisor and dividend by when dividing by a decimal?
You do not need to, but if you must do the following: if the divisor has n digits after the decimal point then multiply by 10n.
