Insert commas suitably and write the names according to International System of Numeration :
(a) 78921092
(b) 7452283
(c) 99985102
(d) 48049831

To do:

We have to insert commas suitably and write the names according to International System of Numeration.

Solution:

We know that,

In International System, there are ones, tens, hundreds, thousands, and millions.

The first comma is placed after the three digits from the right to mark thousands, and 

The second comma is placed after three more digits on the left to mark the millions. 

The commas are placed after every 3 digits from the right in this system.

Therefore,

(a) 78921092 = 78,921,092

In word format: 

Seventy-eight million nine hundred twenty-one thousand ninety-two. 

(b) 7452283 = 7,452,283

In word format: 

Seven million four hundred fifty-two thousand two hundred eighty-three.

(c) 99985102 = 99,985,102

In word format: 

Ninety-nine million nine hundred eighty-five thousand one hundred two.

(d) 48049831 = 48,049,831

In word format: 

Forty-eight million forty-nine thousand eight hundred thirty-one.
