Answer:
0.555, 5.005, 5.55, 5.505
Explanation:
The first one is 0.555 because it doesn't even have 5 its almost 0. That's an easy way to see that its smaller if the number in front of the . (decimal point) is smaller than the other numbers.
The rest of them are harder. They all start with 5. So you have to look at the decimals or the numbers after the dot (.)
5.005 is the next smallest because it has .005 that means its barely over 5. You can look at the amount of 0's after the decimal point to see how little its over the number.
The next is 5.55. Don't be confused by the 0 in 5.505. Think of it this way. 5.505 is 505 points over 5. 5.55 is only 55 points over.
