Question

Aduceti urmatoarele 5 fractii la forma ireductibila: $\frac{14}{9}$ ; $\frac{21}{9} ; \frac{105}{9}$ ; $\frac{125}{9}$ ; $\frac{131}{99}$ .DAU 11 PCT+CORONITA DOAR PT ASTA!!

Answer 1

14 / 9 =  ireductibila          14 = 2·7   ; 9= 3²
21 /9 = 7 /3 
105 / 9 = 35 /3 
125 / 9  =  ireductibila  125 = 5³    si 9= 3²
131 / 99 = ireductibila           99 = 9 ·11   si  131 nu se divide cu 9 ; 11 

Answer 2

$\dfrac{14}{9} \ este\ ireductibila.$

$\dfrac{21}{9}^{(3}=\dfrac{7}{3}$

$\dfrac{105}{9}^{(3}=\dfrac{35}{3}$

$\dfrac{125}{9}\ este\ ireductibila$

$\dfrac{121}{99}^{(11} = \dfrac{11}{9}$
