Shape 1
We know that number 1 fits into the big rectangle 8 times so we know the answer to that is 1/8.
Shape 2
We know that number 2 fits into number 1 twice and we know that double 8 is 16 so the answer to number 2 is 1/16.
Shape 3
We know that number 2 fits into number 3 three times and we know that the answer for number 2 is 1/16 so three lots of that will be 3/16.
Shape 4
We know that number 4 fits into every 1/8 twice. This is because if you put a whole number 4 in an 1/8 and split number 4 is half, you can put one half in the bottom left corner and the other half in the bottom right corner. If 2 fit in every 1/8, you have to do 2x8 which we know is 16. The answer to number 4 must be 1/16.
Shape 5
The answer to shape 5 is 1/8. This is because 2 fit in every quarter and we know that 2x4 is 8 so the answer must be 1/8.
Shape 6
We know that the answer to number 6 is 1/16 because 4 fit in every quarter and we know that 4x4 is 16 so the answer must be 1/16.
Shape 7
We know that 3 lots of number 8 fit into number 7. The answer to number 8 is 1/32 so 3 lots of that is 3/32.
Shape 8
We know that it is 1/32 because 2 of them fit into every 1/16. We know that 2 16 is 32 so the answer is 1/32.
Shape 9
Because we know that number 6 is 1/16, 1/32 because it fits in to number 6 twice.
Shape 10
Because shape 9 is 1/32, shape 10 has to be 1/64 because it fits into number 9 twice.
We hope we have convinced you about these 10 shapes.
