Shape 1: The whole rectangle was split into quarters and shape 1 was half of one of the quarters so it would equal 1/8.
Shape 2: Shape 2 was half the size of shape one so if you half 1/8 you would get 1/16.
Shape 3: Shape 3 is the same as shape 2 and shape 1 added together and 1/8 equals 2/16 so 1/16 add 2/16 equals 3/16.
Shape 4: Think of shape 4 as two triangles each triangle is worth 1/32 I worked this out by looking at the 1/8 box it is in there is four triangles in the box, it then equals 1/32.
Shape 5: You can fit 8 shape 5`s into the rectangle so it is 1/8.

Shape 7: I solved shape 7 similar to shape 4.
Shape 8: 1/8 takeaway shape 7 equals shape 8.
