a) $0.(3) = \frac{3}{9} = \frac{1}{3}$; $0.(1) = \frac{1}{9}$; $0.(5) = \frac{5}{9}$; $0.(7) = \frac{7}{9}$. б) $0.(13) = \frac{13}{99}$; $0.(27) = \frac{27}{99} = \frac{3}{11}$; $0.(45) = \frac{45}{99} = \frac{5}{11}$; $0.(54) = \frac{54}{99} = \frac{6}{11}$. в) $0.(128) = \frac{128}{999}$; $0.(123) = \frac{123}{999} = \frac{41}{333}$; $0.(945) = \frac{945}{999} = \frac{35}{37}$; $0.(138) = \frac{138}{999} = \frac{46}{333}$. г) $0,0(3) = \frac{3}{90} = \frac{1}{30}$; $0,0(72) = \frac{72}{990} = \frac{4}{55}$; $0,00(13) = \frac{13}{9900}$; $0,0(549) = \frac{549}{990} = \frac{61}{110}$. д) $2.(8) = 2 \frac{8}{9} = \frac{26}{9}$; $3.(14) = 3 \frac{14}{99} = \frac{311}{99}$; $7.(12) = 7 \frac{12}{99} = 7 \frac{4}{33} = \frac{235}{33}$; $3,0(27) = 3 \frac{27}{990} = 3 \frac{3}{110} = \frac{333}{110}$. е) $0,12(0) = \frac{120 - 12}{900} = \frac{108}{900} = \frac{3}{25}$; $3,37(0) = 3 \frac{370 - 37}{900} = 3 \frac{333}{900} = 3 \frac{37}{100} = \frac{337}{100}$; $0,005(0) = \frac{50 - 5}{9000} = \frac{45}{9000} = \frac{1}{200}$.
