As shown in the right figure, the area of the shadow part in the quadrilateral accounts for 16% of the area of the circle and 15% of the area of the quadrilateral; the area of the shadow part in the triangle accounts for 19% of the area of the triangle and 18% of the area of the circle______ ．

As shown in the right figure, the area of the shadow part in the quadrilateral accounts for 16% of the area of the circle and 15% of the area of the quadrilateral; the area of the shadow part in the triangle accounts for 19% of the area of the triangle and 18% of the area of the circle______ ．

The area of quadrilateral is the area of circle: 16 △ 15 = 56, the area of triangle accounts for the area of circle: 18 △ 19 = 98, the simplest integer ratio of circle, quadrilateral and triangle is: 1:56:98 = 24:20:27, so the answer is: 24:20:27
