Final answer:
The largest share is 30 bags.
Step-by-step explanation:
To find the largest share, we need to determine the ratio between the smallest share and the largest share. Since the ratio between the smallest and largest shares is 3:5, we can set up a proportion to find the largest share:
3/5 = 18/L
Cross multiplying, we get:
3L = 18 * 5
Simplifying, we find that the largest share is:
L = 90/3 = 30 bags
