Question

scrieti sub forma de fractie ordinara ireductibila numerele:-2,1(6);0,(6);1,2;-0,(36).dau 100 pct si coroana

Answer 1

$-2,1(6) = -(\frac{216-21}{90} ) = - \frac{195}{90} = -\frac{13}{6}$

$0,(6) =\frac{6}{9}  = \frac{2}{3}$

$1,2 = \frac{12}{10} = \frac{6}{5}$

$-0,(36) = -\frac{36}{99} = -\frac{4}{11}$
