Explicație pas cu pas:
a)
[tex](\frac{4}{3} *\frac{3}{2} +\frac{14}{3} )*\frac{9}{40} =\frac{16}{3} *\frac{9}{40} =\frac{6}{5}[/tex]
b)
[tex](\frac{4}{5} -\frac{8}{15} *\frac{3}{4} )*\frac{25}{18} =(\frac{4}{5} -\frac{2}{5} )*\frac{25}{18} =\frac{2}{5} *\frac{25}{18} =\frac{5}{9}[/tex]
c)
[tex]\frac{14}{15} *(\frac{7}{4} +\frac{27}{8} *\frac{2}{9}) =\frac{14}{15} *(\frac{7}{4} +\frac{3}{4} )=\frac{14}{15} *\frac{10}{4} =\frac{7}{3}[/tex]
