(2 5/6+1 3/4 ):1/2,4​

Answer 1

Ответ:

11

Пошаговое объяснение:

(2$\frac{5}{6}$ + 1$\frac{3}{4}$) : $\frac{1}{2.4}$

((2 + 1) + ($\frac{5}{6}$ + $\frac{3}{4}$)) : $\frac{1}{\frac{12}{5} }$

(3 + $\frac{19}{12}$) : $\frac{5}{12}$

(3 + 1 $\frac{7}{12}$) * $\frac{12}{5}$

4$\frac{7}{12}$ * $\frac{12}{5}$

$\frac{55}{12}$ * $\frac{12}{5}$ = 11

Answer 2

$(2\frac{5}{6}+1\frac{3}{4}):\frac{1}{2,4}=((2+1)+(\frac{5}{6}+\frac{3}{4})):\frac{1}{\frac{12}{5} }=(3+\frac{19}{12}):\frac{5}{12}=(3+1\frac{7}{12})*\frac{12}{5}=\\ \\ (3+1+\frac{7}{12})*\frac{12}{5}= (4+\frac{7}{12})*\frac{12}{5}=4\frac{7}{12}*\frac{12}{5}=\frac{55}{12}*\frac{12}{5}=11$
