we have
1/3 < x < 6/5
verify each number
For x=0
1/3 < 0 < 6/5 -------> its not true
For x=1/3
1/3 < 1/3 < 6/5 -----> its not true
For x=4/5
1/3 <4/5 < 6/5
convert to decimal number
0.33 < 0.8 < 1.2 ------> it's true
For x=1.2
0.33 < 1.2 < 1.2 -----> it's not true
For x=-3
0.33 < -3 < 1.2 -----> it's not true
