The correct option is C 7
Total number of days = 49
Number of days in each week = 7
Total number of weeks in 49 days = 49 ÷ 7
Let us apply repeated subtraction to find the number of weeks.
49 - 7 = 42
42 - 7 = 35
35 - 7 = 28
28 - 7 = 21
21 - 7 = 14
14 - 7 = 7
7 - 7 = 0
After subtracting 7 seven times from 49, we get 0.
Thus, 7 weeks will form 49 days.
