Let us take a random 9 digit number - 338652931, and see how it gets decomposed.

Here, PV = Place Value

Digit 1 PV = 1 × 1	1
Digit 2 PV = 3 × 10	30
Digit 3 PV = 9 × 100	900
Digit 4 PV = 2 × 1000	2000
Digit 5 PV = 5 × 10000	50000
Digit 6 PV = 6 × 100000	600000
Digit 7 PV = 8 × 1000000	8000000
Digit 8 PV = 3 × 10000000	30000000
Digit 9 PV = 3 × 100000000	300000000

As mentioned above, the smallest 9 digit number is called a hundred million. It is written as 1, followed by 8 zeros. However, just the placement of the comma in the two different number systems gives this number two different names. The Indian system of numbers follows the 3:2:2 system of placing commas, so the smallest 9 digit number would be written as 10,00,00,000. The 8^th digit from the right denotes the start of a crore, thus, this number would be called 10 crores in the Indian number system. Let us now look at the 3:3:3 system of comma placement in the International number system. This number would be written as 100,000,000. Since the second comma after the 6^th digit from the right denotes the start of a million, this number would be called a hundred million in the International number system.
