The diameter of the moon is approximately one fourth of the diameter of the earth. Find the ratio of their surface areas.

Explanation

To find the ratio of the surface areas of the Moon and the Earth, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the relationship between the diameters**:
- Let the diameter of the Earth be \( d_e \).
- Given that the diameter of the Moon \( d_m \) is one-fourth of the diameter of the Earth, we can express this as:
\[
