Hi There
The first thing you must do is divide the numerator by their denominator
-1/6 = -0.16
5/3= 1.16
-5/6= -0.83
Now we can see which one is the greatest and least
-0.83 < -0.16 < 1.16 ( That's the answer)
Now you might asking yourself why -0.83 is lest than -0.16 ?
Well the reason is because when the negative number is farter zero.. it is lest than the one that near to the zero. So that's why
I hope that's help and if you have questions please let me know :)
