Answer:
86 books
Step-by-step explanation:
A stack of books is 43 inches tall.
Each book is 
inch thick.
To find the number of books in tha stack, divide the height of the stack by the height of the book:
The division by the fraction is equivalent to the multiplication by the fraction 
so
You just need to break it into parts. The first rectangle is the tall one. To find the area of this one, just multiply the tall side by the short side on top.
8 x 2 = 16
The second rectangle is the long one on the bottom. If the whole bottom side is 5 units, then you need to subtract 2 from that.
3 x 1 = 3
16 + 3 = 19 units, so the area of the entire shape would be 19 units^2. Hope this helps! :)

If it is less than full it means it is anything below 5/5 or 6/6, so they both have less than full water bottles...
If you meant less than half full, Josan has 0.5/5 less than half, so yes, They should stop in this case as well.
