Ответ:
- \(\frac{2}{11}+\frac{1}{9}=\frac{18+11}{99}=\frac{29}{99}=0,(29)\);
- \(\frac{8}{13}+\frac{2}{3}=\frac{24+26}{39}=\frac{50}{39}=1,(28)\);
- \(\frac{1}{3}+1,25=0,(3)+1,25=1,58(3)\);
- \(\frac{1}{6}+0,33=0,1(6)+0,33=0,49(6)\);
- \(\frac{3}{14}\cdot1,05=\frac{3}{14}\cdot\frac{21}{20}=\frac{9}{40}=0,225\);
- \(\frac{7}{9}\cdot1,7=\frac{7}{9}\cdot\frac{17}{10}=\frac{119}{90}=1,3(2)\).
Ответ: 1) 0,(29); 2) 1,(28); 3) 1,58(3); 4) 0,49(6); 5) 0,225; 6) 1,3(2).
