1.[tex]\frac{5}{7}-\frac{2}{5}=?[/tex]
First find the LCD which is 35
[tex]\frac{25}{35}-\frac{14}{35}=\frac{11}{35}[/tex]

2.[tex]\frac{7}{8}-\frac{3}{5}=?[/tex]
Find the LCD which is 40
[tex]\frac{35}{40}-\frac{24}{40}=\frac{11}{40}[/tex]

3.Change to improper:
2[tex]\frac{1}{5}=\frac{11}{5}[/tex]
[tex]n=\frac{1}{3}(\frac{11}{5}[/tex]
[tex]n=\frac{11}{15}

Hope this helps =)
