------------------------------------------------------------------------------------------------
−3/4 = -0.75
0.5 = 0.5
2/3 = 0.6667
-7/3 = -2.3333
1.2 = 1.2

Arrange them
------------------------------------------------------------------------------------------------
-7/3 (-2.3333) , −3/4( -0.75) , 0.5 (0.5) , 2/3 (0.6667) , 1.2 (1.2)

Answer 2

It would be easier to convert all of these to decimals first
-3/4 = -0.75
2/3 ≈ 0.67
-7/3 ≈ -2.33

Order
-2.33, -0.75, 0.5, 0.67, 1.2
or
-7/3, -3/4, 0.5, 2/3, 1.2
