Answer:
872.41, 873.15, 877.142, 879.190
Explanation:
When we are comparing numbers, we are doing it from left to right, digit by digit. Let's compare first two numbers: 872.41 and 873.15. 8 is equal to 8, so we can't say, what is more or less. 7 = 7, tie again. But 2 < 3. So, digit from left number is less than digit from second number. Therefore, first number is less than second number, or 872.41 < 873.15.
You compare many times these numbers with each other, and you will get that: 872.41 < 873.15, 873.15 < 877.142, 877.142 < 879.190.
This way, right answer is 872.41, 873.15, 877.142, 879.190.
