a) [tex] \frac{7}{12}( \frac{23+4}{27} ) = \frac{7}{12} [/tex]
b) [tex] \frac{2}{34} ( \frac{17+51*3}{15} )= \frac{2}{34} * \frac{170}{15}= \frac{2*5}{15} = \frac{2}{3 \frac{x}{y} } [/tex]
c) [tex] \frac{24}{35} * \frac{18*3+2*5+11}{75} = \frac{24}{35} *\frac{75}{75} = \frac{24}{35} [/tex]
la d) consider a fi o greseala de exercitiu, pentru ca nu exista o modalitate pentru a da factor comun la toate cele 3 inmultiri
