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.
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 .
How do you check the answer to a decimal division question?
Multiply the quotient by the divisor to result in the dividend.If dividend/divisor=quotient, then dividend=quotient x divisor
When dividing decimalswhat must you do if there is a decimal in the divisor?
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
