Hello,
[tex]\dfrac{7}{5}*\dfrac{-3}{12}+(\dfrac{7}{5}+\dfrac{5}{12})\\=\dfrac{7}{5}(\dfrac{-3}{12}+1)+\dfrac{5}{12}\\=\dfrac{7}{5}(\dfrac{-3+12}{12})+\dfrac{5}{12}\\\\=\dfrac{7}{5}(\dfrac{9}{12})+\dfrac{5}{12}\\\\=\dfrac{7*9+5*5}{12*5}\\=\dfrac{63+25}{12*5}\\\\=\dfrac{88}{60}\\\\=\dfrac{22}{15}\\\\[/tex]
hope this helps
