I’m having a hard time understanding your question
Answer:
6.338
this is the same because thousandths means 3 decimal places and it already has only 3 places, so it is already rounded to the thousandths. Rounded to hundredths place would be 6.34 and tenths would be 6.3.
Assuming you need to find a multiple of both 3 and 11 to be your answer, the answer should be 33 days.
