Answer

To determine whether the statements "3 in A" and "9 in A" are true or false, we can follow these steps:

### Step 1: Identify the set A
We have the set A defined as:
\[ A = \{1, 3, 5, 7, 9\} \]

### Step 2: Check if 3 is in A
We need to see if the number 3 is one of the elements in set A. Looking at the elements of A:
- The elements are 1, 3, 5, 7, and 9.
- Since 3 is listed as one of the elements, we conclude that:
\[ 3 \in A \] (True)

### Step 3: Check if 9 is in A
Next, we check if the number 9 is also one of the elements in set A. Again, looking at the elements of A:
- The elements are 1, 3, 5, 7, and 9.
- Since 9 is listed as one of the elements, we conclude that:
\[ 9 \in A \] (True)

### Conclusion
Both statements "3 in A" and "9 in A" are true.

### Final Answer
- The statement "3, 9 in A" is **True**.
