Ответ:
[tex]\displaystyle32\frac{3}{10}[/tex]
Пошаговое объяснение:
[tex]\displaystyle \frac{4}{5}\cdot 16 \frac{3}{20}+\frac{2}{3}\cdot16 \frac{3}{20}+\frac{8}{15}\cdot 16 \frac{3}{20}=16 \frac{3}{20}\cdot(\frac{4}{5}+\frac{2}{3}+\frac{8}{15})=\\\\\\16 \frac{3}{20}\cdot(\frac{12}{15}+\frac{10}{15}+\frac{8}{15})= \frac{323}{20}\cdot\frac{30}{15}= \frac{323}{20}\cdot2= \frac{323}{10}=32\frac{3}{10}[/tex]
