1) In the flower, there is one red trapezoid, six yellow hexagons and 10 green triangles. The ratio of red trapezoids to yellow hexagons is 1:6, the ratio of red trapezoids to green triangles is 1:10 and the ratio of yellow hexagons to green triangles is 6:10 = 3:5.
2) In one copy, there is one red trapezoid, six yellow hexagons and 10 green triangles.
So in two copies, 2*1 = 2 red trapezoids, 2*6 = 12 yellow hexagons and 2*10 = 20 green triangles.
