#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%#
