Ответ:
- \(\frac{7}{9}-0.6=\frac{7}{9}-\frac{3}{5}=\frac{35-27}{45}=\frac{8}{45}\).
- \(0.34+\frac{8}{11}=\frac{17}{50}+\frac{8}{11}=\frac{187+400}{550}=\frac{587}{550}=1\frac{37}{550}\).
- \(7\frac{5}{6}-4.55=\frac{47}{6}-\frac{91}{20}=\frac{470-273}{60}=\frac{197}{60}=3\frac{17}{60}\).
- \(5.375-1\frac{3}{19}=\frac{43}{8}-\frac{22}{19}=\frac{817-176}{152}=\frac{641}{152}=4\frac{33}{152}\).
Ответ: 1) 8/45; 2) 1 37/550; 3) 3 17/60; 4) 4 33/152.
