$7/9 = 0.bar7 ~~ 0.778$

$7/9 = 77 7/9% ~~ 77.78%$

$7/9$ is one of the awkward fractions which do not give an exact decimal, it recurs.

You have to find the decimal by dividing: $7 div 9$

$9|ul7.0000$
$" "0.77777..." "larr$ the 7 recurs.

You can write this as $0.bar7" or " 0.dot7$

Or show it to a required number of decimal places - usually 2 or 3.

$7/9 ~~ 0.778$

The decimal gives you the percent immediately because the first 2 decimal places represent hundredths.

$7/9 ~~ 77.78%$

This could also be given as $77 7/9%$
