Answer:
Step-by-step explanation:
[tex]\frac{7}{3}*\frac{2}{5}+\frac{1}{6}*\frac{3}{9}-\frac{2}{5}*\frac{1}{9}\\\\=\frac{14}{15}+\frac{1}{18}-\frac{2}{45}\\[/tex]
LCD = 90
[tex]=\frac{14*6}{15*6}+\frac{1*5}{18*5}-\frac{2*2}{45*2}\\\\=\frac{84}{90}+\frac{5}{90}-\frac{4}{90}\\\\=\frac{84+5-4}{90}\\\\=\frac{85}{90}\\\\=\frac{17}{18}[/tex]
