Write the largest 7-digit number. Write the next five numbers. Give their names in Indian system of numeration.

Answer

**Step-by-Step Solution:**

1. **Identify the Largest 7-Digit Number**:
The largest digit in the decimal system is 9. Therefore, the largest 7-digit number is formed by using the digit 9 in all seven places.
- Largest 7-digit number = 9999999

2. **Find the Next Five Numbers**:
To find the next five numbers, we will add 1 to the largest 7-digit number repeatedly.
- Next number: 9999999 + 1 = 10000000
- Next number: 10000000 + 1 = 10000001
- Next number: 10000001 + 1 = 10000002
- Next number: 10000002 + 1 = 10000003
- Next number: 10000003 + 1 = 10000004

3. **Write the Names in Indian System of Numeration**:
Now, we will write the names of these numbers in the Indian system of numeration.
- 9999999 = Ninety-nine lakh ninety-nine thousand nine hundred ninety-nine
- 10000000 = One crore
- 10000001 = One crore one
- 10000002 = One crore two
- 10000003 = One crore three
- 10000004 = One crore four

**Final Answer**:
- Largest 7-digit number: 9999999 (Ninety-nine lakh ninety-nine thousand nine hundred ninety-nine)
- Next five numbers:
- 10000000 (One crore)
- 10000001 (One crore one)
- 10000002 (One crore two)
- 10000003 (One crore three)
- 10000004 (One crore four)
