Решите 1) 4 9/9*1 1/32*1 1/5-(2 11/4- 2 2/35)*4 2/3

4 $\frac{9}{9}$ *1 $\frac{1}{32}$ *1 $\frac{1}{5}$ -(2 $\frac{11}{4}$ - 2 $\frac{2}{35}$ ) * 4 $\frac{2}{3}$ = -6 $\frac{91}{240}$
1)2 $\frac{11}{4}$ - 2 $\frac{2}{35}$ =2 $\frac{97}{140}$
2)2 $\frac{97}{140}$ * 4 $\frac{2}{3}$ =12 $\frac{17}{30}$
3)4 $\frac{9}{9}$ *1 $\frac{1}{32}$ *1 $\frac{1}{5}$ =5 $\frac{5}{32}$ *1 $\frac{1}{5}$ =6 $\frac{3}{16}$
4)6 $\frac{3}{16}$ -12 $\frac{17}{30}$ =-6 $\frac{91}{240}$
