Answer:
because the smaller potato cube has a smaller volume to area ratio that means smaller absorption time.
Step-by-step explanation:
there are 2 things to consider:
1°) if the iodine enters at constant rate to the cube, the time required to completely absorb all the iodine is proportional to the mass of the potato cube ( more mass that is required to absorb, means more iodine should enter the cube at same rate and therefore more time) . also, the mass of the potato is proportional to the volume of it (assuming constant density)
2°) if we consider 2 potatoes with same mass, the time required is inversely proportional to the area of contact with the solution of iodine ( more area means more iodine is able to enter per mm2 of potato's surface with the same mass and consequently less time)
therefore, the time is proportional to the ratio of volume and area of the cube. Since the smaller cube has a smaller ratio, takes less time to be completely purple

Answer:
1/3
Step-by-step explanation:
The best option here would to make everything equivalent of each other.
3/4 --> 18/24
1/3 --> 8/24
-3/6 --> -12/24
-5/8 --> -15/24
Now which numerator is closer to zero? 1/3 (8/24), so there is your answer.
