687,521,000,000
OD 612,365,963,140
685,562,777,777

Answer 1

A because when we look at the 3 largest digits, 687, 685, and 612, we could find out that A is correct.

Answer 2

The group of numbers that are ordered from greatest to least is A) 687,521,000,000, 685,562,777,777, 612,365,963,140

How to find the group of numbers ?

Start by looking at the highest place value, which in this case is the hundreds of billions place. If the numbers are the same in this place, we move to the next place value, and so on, until we find a difference.

Since all three numbers start with 6 in the hundreds of billions, we look at the tens of billions place. Here, both the first and the second numbers have 8, but the third number has 1, making it the smallest. Between the first two numbers, the first number has a 7 in the billions place, while the second number has a 5, making the first number the largest.

The order is therefore:

1. 687,521,000,000 (largest)
2. 685,562,777,777
3. 612,365,963,140 (smallest)
