For this case we have the following fractions:
[tex]\frac {1} {3} = 0.3333\\\frac {5} {6} = 0.8333\\\frac {3} {5} = 0.6[/tex]
So we have to:
[tex]0.3333 <0.6 <0.8333[/tex]
This is equivalent to:
[tex]\frac {1} {3} <\frac {3} {5} <\frac {5} {6}[/tex]
Answer:
[tex]\frac {1} {3} <\frac {3} {5} <\frac {5} {6}[/tex]
The answer is Option A
