Answer 1

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