One can stop writing the dividend with more zers after the decimal (C) When the quotient is accurate to a desired number of decimal places.
When you are dividing to express a fraction as a decimal, you should continue adding zeros after the decimal point in the dividend until you have reached the desired number of decimal places. This is because each additional zero that you add will allow you to calculate one more decimal place in the quotient.
For Instance ;
1/5 expressed as a decimal would give;
However, when asked to round to 4 decimal places , we would have
1/5 = 0.2000
The addition of zeros doesn't change the value of the result obtained . However, it allows the result to be expressed to the stated level of precision in the question.
Hence, the correct answer is Option (C).
