Question

Scrieți sub forma de fractie ordinara ireductibilă numerele : -2,1(6) , 0,(6) , 1,2 , -0,(36) va rogggg

Answer 1

$- 2.1(6) = - 2 \frac{16 - 1}{90} = - 2 \frac{15}{90} = - 2 \frac{1}{6} = - \frac{2 \times 6 + 1}{6} = - \frac{13}{6}$

$sau$

$- 2.1(6) = - \frac{216 - 21}{90} = - \frac{195}{90} = - \frac{39}{18} = - \frac{13}{6}$

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

$1.2 = \frac{12}{10} = \frac{6}{5}$

$- 0.(36) = - \frac{36}{99} = - \frac{12}{33} = - \frac{4}{11}$
