Write the number corresponding to :

(1 × 10,00,000) + (2 × 1,00,000) + (3 × 10,000) + (4 × 100) + (6 × 10) + (9 × 1).

To find the number corresponding to the expanded form, we will calculate each term and then sum them up:

1 × 10,00,000 = 10,00,000

2 × 1,00,000 = 2,00,000

3 × 10,000 = 30,000

4 × 100 = 400

6 × 10 = 60

9 × 1 = 9

Now, add these values together:

10,00,000 + 2,00,000 + 30,000 + 400 + 60 + 9 = 12,30,469

Hence, the number corresponding to the given expanded form is 12,30,469.
