Question

Rog rezolvare 2,1(6):0,36(1)-5,(3)

Answer 1

2.1(6):0.36(1)-5.(3)=6- 5.3=0.7

Answer 2

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