Question

Помагите я буду рад если ответите​

Answer 1

$\frac{0,(12)}{0,(6)}+1,(81)=$

1) $0,(12)=\frac{12}{99}=\frac{4}{33}$

2) $0,(6)=\frac{6}{9}=\frac{2}{3}$

3)  $1,(81)=1\frac{81}{99}=1\frac{9}{11}$

$\frac{0,(12)}{0,(6)}+1,(81)=\frac{4}{33}:\frac{2}{3}+1\frac{9}{11}=\frac{4}{33}:\frac{3}{2}+1\frac{9}{11}= \frac{2}{11}+1\frac{9}{11}=1+\frac{11}{11}=1+1=2$

ответ:  2
