No, assuming I read your question correctly. It was a little confusing.

#5 1/3 = 16/3#

#-3 9/18 = -7/2#

so

#16/3 - 7/2 = ((16xx2) - (7xx3))/(3xx2) = (32-21)/6 = 11/6#

#11/6# as a mixed number form is #1 5/6#.

Th answer is #1 5/6# and not #2 5/6#

#5 1/3-3 9/18" "larr# can be simplified

#5 1/3 -2 1/2#

#=2 (?-?)/6" "larr# subtract the whole numbers and find LCD

#= 2 (2-3)/6" "larr# find equivalent fractions

#= 2 (-1)/6#

#= 1 5/6#

Therefore the answer #2 5/6# is not correct.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~another method
#= 2 (2-3)/6#

#= 1 (6+2-3)/6" "larr1 = 6/6#

#= 1 5/6#
