Answer:
40 weeks
Step-by-step explanation:
The relationship between weeks and years is that there are 52 weeks in a year. Given that Shanna attends school for 1 week longer than 3/4 of the year, we need to find the number of weeks she attended school.
To find the number of weeks in 3/4 of a year, we can multiply 52 weeks by 3/4:
= 52 weeks * 3/4
= 39 weeks
Since Shanna attends school for 1 week longer than 3/4 of the year, we add 1 week to the 39 weeks:
= 39 weeks + 1
= 40 weeks
Therefore, Shanna attended school for 40 weeks.
