Answer 1

Ответ:

$0.(27) = \frac{27}{99} = \frac{3}{11} \\ \\ 1.2(4) = 1 \frac{24 - 2}{90} = 1 \frac{22}{90} = 1 \frac{11}{45}$

Answer 2

Ответ:

$0.(27) = \frac{27}{99} = \frac{3 \times 9}{33 \times 3} = \frac{3}{11} \\ 1.2(4) = 1 \frac{24 - 2}{90} = 1 \frac{22}{90} = 1 \frac{11 \times 2}{45 \times 2} = 1 \frac{11}{45}$
