We decided that number 1 goes into each shape 8 times that means it is an 1/8 of the whole rectangle.
We think shape goes into each shape 16 times. We think this because it is double of number 1.
We knew that shape 1 was an 1/8 and shape 2 is a 1/16 its 3/16.
Shape 4 fitted into the rectangle 16 times so it must be 1/16.
Shape 5 is an 1/8 because it fitted in the rectangle 8 times.
Shape number 6 is a 1/16 because it fitted into the rectangle 16 times.
Shape number 7 is 3/32 because it fitted into seven three times .
Shape number 8 fitted into the rectangle 32 times. Also 8 of our shape made 1/4. 8 of them fitted into a quarter 8 times and 4x8 is 32.
Shape number 9 is 1/32 we know this because it fits in 32 times.
Shape number 10 is 1/64 because it fits into the rectangle 64 times and it is half the size of shape 9.
