see the picture attached
we know that
fraction of the shaded figure=Total parts/Shaded parts
case A)
Total parts of the figure=5
Shaded parts of the figure=3
so
fraction of the shaded figure=3/5
case B)
Total parts of the figure=5
Shaded parts of the figure=3
so
fraction of the shaded figure=3/5
case C)
Total parts of the figure=5
Shaded parts of the figure=2
so
fraction of the shaded figure=2/5
case D)
Total parts of the figure=5
Shaded parts of the figure=3
so
fraction of the shaded figure=3/5
the fractions of cases A) B) and D_ are equal
case E)
Total parts of the figure=11
Shaded parts of the figure=5
so
fraction of the shaded figure=5/11
representation of the same fractions amount in the attached figure N 2
case F)
Total parts of the figure=10
Shaded parts of the figure=2
so
fraction of the shaded figure=2/10----> 1/5
representation of the same fractions amount in the attached figure N 2
