1 - 7/9 = 2/9
7/9 + 9/12 = 55/36
12 : 2/3 = 18
9/12 : 3 = 1/4
\(1-\frac{7}{9}=\frac{9}{9}-\frac{7}{9}=\frac{2}{9}\)
\(\frac{7}{9}+\frac{9}{12}=\frac{28}{36}+\frac{27}{36}=\frac{55}{36}\)
\(12:\frac{2}{3}=12x\frac{3}{2}=\frac{36}{2}=18\)
\(\frac{9}{12}:3=\frac{9}{12}x\frac{1}{3}=\frac{9}{36}=\frac{1}{4}\)
