You need to order the following values from least to greatest:
To order negative values you have to remember that the greater the absolute value is, the smaller the negative value will be, for example:
-2 →the absolute value is |2|
-1.5 → the absolute value is |1.5|
|2| is greater than |1.5| which means that -2 is less than -1.5
And remember that the negative values are always less than the positive values.
With this in mind
-1 → |1|
-0.45 → |0.45|
|1|>|0.45| then -1<-0.45
The smaller values is -1, the next one is -0.45 and the greates is 0.4
