If A = {1,2,3,4,5}, then `9 in A`

Answer

To determine whether the element 9 belongs to the set A = {1, 2, 3, 4, 5}, we can follow these steps:

### Step 1: Identify the elements of set A
The elements of set A are given as {1, 2, 3, 4, 5}.

### Step 2: Check if 9 is one of the elements in set A
We need to see if the number 9 is present in the set A. The elements of A are 1, 2, 3, 4, and 5.

### Step 3: Compare the number 9 with the elements of set A
Now, we will compare the number 9 with each element of set A:
- 1 is not equal to 9
- 2 is not equal to 9
- 3 is not equal to 9
- 4 is not equal to 9
- 5 is not equal to 9

Since none of the elements in set A are equal to 9, we can conclude that 9 is not in the set.

### Step 4: State the conclusion
Therefore, we can conclude that the statement "9 in A" is false.

### Final Answer
9 does not belong to the set A.
