Answer:
6.4, 6.45, 6.481, 6.539, 6.557, 6.56
Step-by-step explanation:
First to make this problem more simple, we can make all the numbers have the same digits.
6.4 is the same as 6.400 ( we can just add zeros on the end)
6.56 is the same as 6.560
6.45 is the same as 6.450
Now we should have 6.539, 6.560, 6.400, 6.450, 6.557, and 6.481
Now the easy part is to put them in order from least to greatest
6.4, 6.45, 6.481, 6.539, 6.557, 6.56
If you still dont understand try plotting these on a number line or comment your question!
Hope this helps
