Răspuns:
[tex] \frac{12}{25} [/tex]
Explicație pas cu pas:
Transformam fractiile zecimale in fractii ordinare:
(facem simplificari daca e cazul)
0,2(6)=
[tex] \frac{(26 - 2)}{90} = \frac{24}{90} = \frac{4}{15} [/tex]
1,12=
[tex] \frac{28}{25} [/tex]
1,(3)=
[tex] \frac{4}{3} [/tex]
Inlocuim in exercitiu:
[tex] \frac{4}{15} - \frac{28}{25} + \frac{4}{3} [/tex]
Aducem la acelasi numitor(75)
[tex] \frac{20 - 84 + 100}{75} = \frac{36}{75} = \frac{12}{25} [/tex]
