#2/3 #

Explanation:

to subtract there must be a common denominator, it is not possible to subtract two items that are not the same.

Change # 7/9# to the same denominator as # 2/18#

# 7/9 xx 2/2 = 14/18#

Now that both fractions have the same denominator it is possible to subtract them.

# 14/18 - 2/18 = 12/18#

#12/18 div 6/6 = 2/3 #
