To make this easy, turn these all into a common format: I will use mixed fractions.
You will have [tex] 0\frac{0}{30} , -0 \frac{15}{30} , 1\frac{0}{30} -3 \frac{10}{30} , 6 \frac{0}{30} , 5 \frac{0}{30} , -1 \frac{0}{30} , 4 \frac{6}{30} , and 4 \frac{0}{30} [/tex]
From there, the numbers go -3 10/30 , -1 0/30 , -0 15/30 , 0 , 1 , 4 , 4 6/30 , 5 , 6
