Answer:
3.917, 5.2082, 5.28, 5.8
Explanation:
The first is 3.8 because the 3 is smaller than the 5's. So, this one is obviously first.
Second, 5.2082, we see that another one is 5.28, but if you simplify the number down to only 5.20, we see that the 0 is smaller than the 8.
Thirdly, we have 5.28. The 2 in 5.28 is smaller than the 8 in 5.8, so that is why this is third.
And lastly, we remain the 5.8 as the biggest.
