Answer:
-3/5
-1/2
-0.4
0.6
4/5
Step-by-step explanation:
For this question I converted the fractions to decimals.
-3/5 = -0.6
-1/2 = -0.5
4/5 = 0.8
Start off with the negatives, as they are the lowest numbers. <em>The further they are from zero the lower they get.</em>
-0.6  (-3/5)
-0.5  (-1/2)
-0.4
Now there are only <em>2</em> positive numbers, so order them.
0.6
0.8 (4/5)
Put it all together:
-3/5
-1/2
-0.4
0.6
4/5
