Step-by-step explanation:
Here are the answers to the given problems:
(i) If 156 ÷ __ = 1564, then __ = 23
**Answer:** 156 ÷ **67** = 1564, then **67** = 23
(ii) If 168 ÷ __ = 3960, then __ = 45
**Answer:** 168 ÷ **23** = 3960, then **23** = 45
(iii) If 3960 ÷ __ = 1311, then __ = 89
**Answer:** 3960 ÷ **45** = 1311, then **45** = 89
(iv) If 1311 ÷ __ = 6399, then __ = 61
**Answer:** 1311 ÷ **21** = 6399, then **21** = 61

Please note that for the complete problems (i-iv), I have provided the missing numbers that satisfy the equation when considering the second part of each statement. For example, in (i), if we divide 1564 by the missing number, we should get a quotient of 156, and that missing number should also equal to 23 when we follow the second part of the statement. However, it seems there might be an error in the provided problems or in their transcription, as the numbers do not align with typical division results. Please double-check the problems or provide additional context.
