Write the number corresponding to :

(2 × 10,00,000) + (3 × 1,00,000) + (7 × 1,000) + (9 × 100) + (4 × 10) + (5 × 1).

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

2 × 10,00,000 = 20,00,000

3 × 1,00,000 = 3,00,000

7 × 1,000 = 7,000

9 × 100 = 900

4 × 10 = 40

5 × 1 = 5

Now, add these values together:

20,00,000 + 3,00,000 + 7,000 + 900 + 40 + 5 = 23,07,945.

Hence, the number corresponding to the given expanded form is 23,07,945.
