Ответ:
а) \(6+\frac{3}{5}=6+0.6=6.6\).
б) \(6-\frac{3}{5}=6-0.6=5.4\).
в) \(0.3+\frac{2}{3}=\frac{3}{10}+\frac{2}{3}=\frac{9}{30}+\frac{20}{30}=\frac{29}{30}\).
г) \(0.3-\frac{2}{3}=\frac{9}{30}-\frac{20}{30}=-\frac{11}{30}\).
д) \(0.6-\frac{1}{3}=\frac{3}{5}-\frac{1}{3}=\frac{9}{15}-\frac{5}{15}=\frac{4}{15}\).
е) \(0.6+\frac{1}{3}=\frac{3}{5}+\frac{1}{3}=\frac{9}{15}+\frac{5}{15}=\frac{14}{15}\).
ж) \(0.6-\frac{2}{3}=\frac{9}{15}-\frac{10}{15}=-\frac{1}{15}\).
з) \(0.6+\frac{2}{3}=\frac{9}{15}+\frac{10}{15}=\frac{19}{15}=1\frac{4}{15}\).
Ответ: а) 6,6; б) 5,4; в) 29/30; г) −11/30; д) 4/15; е) 14/15; ж) −1/15; з) 1 4/15.
