In the given diagram, there are 5 unshaded (white) parts and 1 shaded (red) part.
To find the ratio of unshaded sections to shaded sections, we compare the number of unshaded parts to the number of shaded parts:
- Unshaded parts: 5
- Shaded parts: 1
The ratio of unshaded sections to shaded sections is therefore:
5 (unshaded) to 1 (shaded), which can be written as:
5 to 1
So, the correct answer is 5 to 1.
