2,050,000,000
I write 620 billion as 620 billion.
Sixteen point two billion is how I would write it.
To write 205 thousandths, you express it as a decimal: 0.205. This means 205 parts out of 1,000, so it can also be written as the fraction 205/1000. In words, you would say "two hundred five thousandths."
You write 3.56 billion as 3,560,000,000.
It is written as such: CCV
205 x 10^9
=205-200/205*100
