Answer 1

Ответ:

Пошаговое объяснение:

$4\frac{1}{30} +(8\frac{1}{20} -3\frac{1}{5} )=8\frac{53}{60}$

$1)8\frac{1}{20}-3\frac{1}{5} =\frac{161}{20} -\frac{16}{5} =\frac{161}{20} -\frac{64}{20} =\frac{97}{20}$

$2)4\frac{1}{30} +\frac{97}{20} =\frac{121}{30} +\frac{97}{20} =\frac{242}{60} +\frac{291}{60} =\frac{533}{60} =8\frac{53}{60}$
