Write the given numbers in expanded form: 900999

Answer

To write the number 900999 in expanded form, we will break it down according to the place values of each digit.

### Step-by-Step Solution:

1. **Identify the digits and their place values**:
- The number 900999 has six digits.
- From left to right, the place values are:
- 9 (in the lakhs place)
- 0 (in the ten thousands place)
- 0 (in the thousands place)
- 9 (in the hundreds place)
- 9 (in the tens place)
- 9 (in the ones place)

2. **Write each digit multiplied by its place value**:
- 9 in the lakhs place: \(9 \times 1,00,000\) (which is 9 lakhs)
- 0 in the ten thousands place: \(0 \times 10,000\) (which is 0)
- 0 in the thousands place: \(0 \times 1,000\) (which is 0)
- 9 in the hundreds place: \(9 \times 100\) (which is 900)
- 9 in the tens place: \(9 \times 10\) (which is 90)
- 9 in the ones place: \(9 \times 1\) (which is 9)

3. **Combine the expanded terms**:
- Now, we can combine these values:
\[ 9 \times 1,00,000 + 0 \times 10,000 + 0 \times 1,000 + 9 \times 100 + 9 \times 10 + 9 \times 1 \]
- This simplifies to:
\[ 9,00,000 + 0 + 0 + 900 + 90 + 9 \]

4. **Final expanded form**:
- Therefore, the expanded form of 900999 is:
\[ 9,00,000 + 900 + 90 + 9 \]

### Final Answer:
The expanded form of 900999 is:
\[ 9,00,000 + 900 + 90 + 9 \]
