Question

решите пожалуйста!!!​

Answer 1

Ответ:

$4\frac{11}{15}*2 \frac{5}{13}-2 \frac{11}{15}*2 \frac{5}{13\\}=4\frac{10}{13} \\\\1) 4 \frac{11}{15}*2 \frac{5}{13}= \frac{71}{15} *\frac{31}{13}= \frac{2201}{195} \\\\2) 2\frac{11}{15} *2\frac{5}{13} =\frac{41}{15}* \frac{31}{13} =\frac{1271}{195}\\\\3) \frac{2201}{195}- \frac{1271}{195} =\frac{930}{195}= \frac{62}{13}=4 \frac{10}{13}$
