Помогите решить примеры с дробями 1) 3 5/6 + 2 7/15-1 29/30= 2) 4 1/6*3 3/5= 3) 1 2/13...

Решите задачу:

$1)3\frac{5}{6}+2\frac{7}{15}-1\frac{29}{30}=4+\frac{25+14-29}{30}=4+\frac{10}{30}=4\frac{1}{3}$

$2)4\frac{1}{6}*3\frac{3}{5}=\frac{25}{6}*\frac{18}{5}=15$

$3)1\frac{2}{13}:1\frac{4}{11}=\frac{15}{13}:\frac{15}{11}=\frac{15}{13}*\frac{11}{15}=\frac{11}{13}$

$4)2\frac{2}{3}*1\frac{1}{8}:6\frac{2}{3}=\frac{8}{3}*\frac{9}{8}:\frac{20}{3}=3*\frac{3}{20}=\frac{9}{20}$

$5)2:2\frac{2}{3}+1\frac{4}{5}*3\frac{1}{3}-2\frac{5}{6}=2:\frac{8}{3}+\frac{9}{5}*\frac{10}{3}-2\frac{5}{6}=2*\frac{3}{8}+6-2\frac{5}{6}=\\=\frac{3}{4}+3\frac{1}{6}=3+\frac{9+2}{12}=3+\frac{11}{12}=3\frac{11}{12}$
