Which list is in order from least to greatest?

|−3.5| ,  |4.2|,  |−9|

|−9|, |4.2|, |−3.5|

|−9|, |−3.5|, |4.2|

|−3.5|, |−9|, |4.2|

Picture a number line:  The farther to the left, the smaller the number

                                The farther to the right, the larger the number

Step-by-step explanation:

9/5,−2.5,−1.1,−4/5, 0.8

9/5 = 1.8

-4/5 = -0.8

On number line from left to right these are:

-2.5, -1.1, -4/5, 0.8, 9/5

So that is the order from least to greatest

<***|**>

    -2.5        -1.1    -4/5     0       0.8      9/5
