Write the predecessor of each of the following:
600000

Answer

To find the predecessor of the number 600000, we follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Predecessor**:
The predecessor of a number is the number that comes immediately before it. In simpler terms, to find the predecessor, we subtract 1 from the given number.

2. **Write Down the Given Number**:
The number we are working with is 600000.

3. **Subtract 1 from the Given Number**:
We need to perform the operation:
\[ 600000 - 1 \]

4. **Perform the Subtraction**:
When we subtract 1 from 600000, we need to consider the digits:
- The last digit is 0. Since we cannot subtract 1 from 0, we need to borrow from the next digit.
- The second last digit is also 0, and we continue borrowing until we reach the first non-zero digit.
- The first digit (6) will become 5 after borrowing, and all the zeros will turn into 9s.
- Therefore, the calculation looks like this:
- 600000 becomes 599999 after borrowing.

5. **Write Down the Result**:
The predecessor of 600000 is 599999.

### Final Answer:
The predecessor of 600000 is **599999**.
