A ratio of \( 2:2:1 \) describes the relative parts or quantities of three elements compared to each other. Here's what it means:

- For every **2 parts** of the first item, there are **2 parts** of the second item and **1 part** of the third item.
- This ratio can be simplified to **2:2:1** or, equivalently, to **2:2:1** directly (since it’s already in simplest form).

### Example:
If we have a total quantity of 50:
1. Sum of parts in the ratio \( 2 + 2 + 1 = 5 \).
2. Divide the total by this sum: \( 50 \div 5 = 10 \).
3. Distribute according to the ratio:
   - First item: \( 2 \times 10 = 20 \)
   - Second item: \( 2 \times 10 = 20 \)
   - Third item: \( 1 \times 10 = 10 \)

So, in this case, the quantities would be **20, 20, and 10**.
