$\dashrightarrow \sf \frac{4}{5} \: \boxed{?} \: \frac{6}{7}$

LCM of 5 and 7 is 35.

$\dashrightarrow \sf \frac{4 \times 7}{5 \times 7} \: \boxed{?} \: \frac{6 \times 5}{7 \times 5}$

$\dashrightarrow \sf \frac{28}{35} \: \boxed{ < } \: \frac{30}{35}$

$\dashrightarrow \sf 4:5 \: \boxed{ < } \: 6:7$

$\Huge\therefore$6:7 is greater.
