A. 1:8
B. 1:6
C. 1:4
D. 1:3
E. 1:1

The OA is D
The area of the small shaded portion = 18 - 12 = 6;
The area of the large shaded portion = 50 - 32 = 18;

Thus, the ratio of the area of the small shaded portion to the area of the large shaded portion = 6 : 18 = 1 : 3

The correct answer: D

Hope this helps!

The OA is D
The area of the large shaded portion is the difference of the areas of the largest and the second largest squares. That area is 50 - 32 = 18.

The area of the large shaded portion is the difference of the areas of the third largest and the smallest squares. That area is 18 - 12 = 6.

Therefore, the ratio of the area of the small shaded portion to the area of the large shaded portion is 6/18 = 1/3.

Answer: D
