1) Between the pentagons, you take the small number over big number, so 6:14. But we can simplify that more all the way down to 3:7
2) Between the squares, we can do the same thing.... 3:5
3) Between the parallelograms, it would be 2:5
4) Between the hexagons, it would be 4:12, but when we simplify, it becomes 1:3
