First we can simplify 4/6 dividing between two on numerator and denominator
![(4)/(6)=(2)/(3)](https://img.qammunity.org/2023/formulas/mathematics/college/7q9ijl0blodevcdj7fyhgplmom266geysh.png)
then 2/3 and 4/3 are the same number, then option A and -b are wrong the number are the same and cant be greater or less than
we can notice on second number line 4/6 is less than 5/6 then 2/3 is less than 5/6 too
![(2)/(3)<(5)/(6)](https://img.qammunity.org/2023/formulas/mathematics/college/5kjindqtmt8nd8b0pup0ao4972j0z53qiv.png)
then right option is C
