Answer:
The order is 805,000,000 then 8,850,500,805 then 80,850,000,000.
Explanation:
Since there are 2 commas in the first number, and 3 digits in the millionths place, that is the first number. Since there are 3 commas in the second number, and 1 digit in the billionths place, it is the second number because million is smaller than billion. The third number has 2 digits in the billionths place so it is the last number.
