Answer:
54.833, 54.83, 54.03
Explanation:
Compare the numbers starting from the tenths, since the whole numbers are all the same, then the hundredths and so on.
54.830 (This is the second least since its thousandth is smaller)
54.030 (This is the least since its tenth is already the smallest)
54.833 (This is the greatest since it's digits are the largest even until the thousandth)
