By dividing the whole chikki into 6 equal parts in different ways, we get 1⁄6 chikki pieces of different shapes. Are they of the same size?
Answer
Yes — they are the same size, even though their shapes are different.
In the first picture the chikki is cut into 6 rectangles; in the second it is cut into 6 triangles. In both cases the whole chikki has been shared into 6 equal parts, so one part is 1⁄6 chikki either way.
The big idea: a fraction measures how much, not what shape. Six equal pieces of the same chikki must each be 1⁄6 of it, whether they are square, rectangular or triangular.
Try This: fold a square sheet into 6 equal parts in two different ways. Cut them and place one piece of each kind on a weighing balance — they balance.
