Пошаговое объяснение:
[tex]4\frac{1}{30} +(8\frac{1}{20} -3\frac{1}{5} )=8\frac{53}{60}[/tex]
[tex]1)8\frac{1}{20}-3\frac{1}{5} =\frac{161}{20} -\frac{16}{5} =\frac{161}{20} -\frac{64}{20} =\frac{97}{20}[/tex]
[tex]2)4\frac{1}{30} +\frac{97}{20} =\frac{121}{30} +\frac{97}{20} =\frac{242}{60} +\frac{291}{60} =\frac{533}{60} =8\frac{53}{60}[/tex]
