Ответ:
- \(0.79+3.018=3.808\).
- \(4.1-2.8=1.3\).
- \(1.8\cdot0.3=0.54\).
- \(5.4:6=0.9\).
- \(72:0.9=80\).
- \(9:4=2.25=2\frac{1}{4}\).
- \(10:\frac{5}{11}=10\cdot\frac{11}{5}=22\).
- \(2\frac{3}{8}+4\frac{1}{6}=6+\frac{9}{24}+\frac{4}{24}=6\frac{13}{24}\).
- \(6-1\frac{3}{5}=5-\frac{3}{5}=4\frac{2}{5}\).
Ответ: 1) 3,808; 2) 1,3; 3) 0,54; 4) 0,9; 5) 80; 6) 2\(\frac{1}{4}\); 7) 22; 8) 6\(\frac{13}{24}\); 9) 4\(\frac{2}{5}\).
