#1 1/2-7/9=13/18#

To solve #1 1/2-7/9#, one needs to first convert all fractions to improper fractions. We have just one here #1 1/2=3/2# and hence

#1 1/2-7/9=3/2-7/9#.

Now as LCD of denominators #2# and #9# is #18#, we should reduce all fractions so that they have #18# as common denominator.

Hence,

#1 1/2-7/9=3/2-7/9#

= #(3xx9)/(2xx9)-(7xx2)/(9xx2)#

= #27/18-14/18#

= #(27-14)/18=13/18#.
