Answer:
-2 2/3,   -2.5,   1.3,  1 1/2,   3
Step-by-step explanation:
So least to greatest 
First we should look at the negatives
The smallest number is -2 2/3
The second smallest number is -2.5
The third smallest number is   1.3
The fourth smallest number is   1 1/2
The last number should be the biggest number which would be 3 in this problem
To make this easier you can convert all the fraction to decimal points too
-2 2/3 would be around -2.66
1 1/2 would be 1.5
