Răspuns :

2.1(6):0.36(1)-5.(3)=6- 5.3=0.7
[tex]2,1(6)=2 \frac{16-1}{90}=2 \frac{15}{90}(15=2 \frac{1}{6}= \frac{13}{6} [/tex]
[tex]0,36(1)= \frac{361-36}{900}= \frac{325}{900}(25= \frac{13}{26}(13= \frac{1}{2} [/tex]
[tex]5,(3)=5 \frac{3}{9}(3=5 \frac{1}{3}= \frac{16}{5} [/tex]
[tex] \frac{13}{6}: \frac{1}{2}- \frac{16}{5}=[/tex]
[tex]= \frac{13}{6}*2- \frac{16}{5}= [/tex]   se simplifica 6 cu 2 
[tex]= 5)\frac{13}{3}-3) \frac{16}{5}= [/tex]
[tex]= \frac{65}{15}- \frac{48}{15}=[/tex]
[tex]= \frac{17}{15}=[/tex]
[tex]=1,1(3)[/tex]
