Explicație pas cu pas:
[tex](\frac{4}{5} - \frac{8}{15} : \frac{4}{3})- 1\frac{7}{4}=[/tex]
[tex](\frac{4}{5} -\frac{8}{15} * \frac{3}{4} ) - \frac{1*4+7}{4} =[/tex]
[tex](\frac{4}{5}- \frac{2}{5})- \frac{11}{4} =[/tex]
[tex]\frac{2}{5}- \frac{11}{4}=[/tex]
[tex]\frac{8}{20}- \frac{55}{20}=[/tex] [tex]- \frac{47}{20}[/tex]
