Question

calculeaza 1/2:(1-1/2):[1/5+4(1/3+1/3:2)]+1/11

Answer 1

$\frac{1}{2}:(1-\frac{1}{2}):[\frac{1}{5}+4(\frac{1}{3}+\frac{1}{3}:2)]+\frac{1}{11}=\frac{1}{2}:\frac{1}{2}:[\frac{1}{5}+4(\frac{1}{3}+\frac{1}{3}\cdot\frac{1}{2})]+\frac{1}{11}=\\\\1:(\frac{1}{5}+4\cdot\frac{2+1}{6})+\frac{1}{11}=1:(\frac{1}{5}+2)+\frac{1}{11}=1:\frac{1}{11}+\frac{1}{11}=\frac{11}{1}+\frac{1}{11}=\frac{122}{11}$
