There are 180 school days in the academic year. Aliyah packs a lunch half the time. Becky packs her lunch half as much as Aliyah. How many days a year does Becky pack her lunch? Let's be accurate as possible.
Aliyah packs her lunch the time, so in 180 school days / 2 = she packs her lunch 90 times. Becky packs her lunch as much as Aliyah, so 90 times / 2 = 45 times a year.
The answer: 45.
