Question

You divide a bag of 35 potatoes into fifths (five equal parts), what is the “whole” which you shared equally? In which case is a “whole” not one (1)?  

Answer 1

If the size and mass of each of the 35 potatoes in the bag are equal, we can divide it into 5 parts of equal "whole" numbers.

Otherwise, if the mass and size of each of the 35 potatoes in the bag differ from each other, then when we divide it into 5 equal parts, it may not correspond to the whole numbers.
