6) 3/5=18/30
2)2/15=4/30
3)1/10=3/30
3)19/10=57/30
(18/30+4/30-3/30):57/30
19/30:57/30=0(3)/30
Sper ca n-am greșit si noroc
[tex] \frac{3}{5} + \frac{2}{15}- \frac{1}{10} ) : \frac{19}{10} [/tex]
aducem la acelasi numitor 30
[tex]( \frac{18}{30} + \frac{4}{30} - \frac{3}{30} ): \frac{19}{10} [/tex]
[tex] \frac{19}{30} X \frac{10}{19} = \frac{10}{30} = \frac{1}{3} [/tex]
