Answer:
A) 1. Multiply the divisor by a multiple of 10 to create an integer divisor. 2. Multiply the dividend by the same multiple of 10 as step 1. 3. Divide, and apply the rules for dividing signed numbers.
Step-by-step explanation:
In Mathematics, divisor is the number by which the dividend should be divided.
Now, if we want to divide a decimal by another decimal, to make things easy we have to transform both numbers from decimals to integer form to make direct division easier.
The first step will be to multiply the divisor by a multiple of 10. The multiple of 10 will depend on the number of decimal places.
The second step is to do the same to the dividend.
The last step would be to divide the integers by applying rules of division of numbers.
The correct option is Option A:
