The answer would be yes because 2/5 is less than half of Josan's water bottle.
Step-by-step explanation:
We'll start by figuring if either is less than half full. We know that half of 5/6 = 3/6, so we can cross of Andrea's bottle fill amount for a reason to stop. Half of 5 = 2.5, and since 2 is less than 2.5 (or half), they can stop for water.
Hope I helped and good luck!
