Răspuns :
aducem fractiile din paranteza la acelasi numitor(70) si obtinem:
[tex] \frac{10}{1}( \frac{35 + 10 - 7}{70} )[/tex]
calculam si aici si obtinem:
[tex] \frac{10}{1} \times \frac{38}{70} [/tex]
se simplifica si obtinem:
[tex] \frac{10}{1} \times \frac{19}{35} [/tex]
simplificam 10 cu 35 si obtinem:
[tex] \frac{2}{1} \times \frac{19}{7} [/tex]
calculam inmultirea si obtinem:
[tex] \frac{38}{7} [/tex]
Sper ca te am ajutat! : )
[tex] \frac{10}{1} ( \frac{1}{2} + \frac{1}{7} - \frac{1}{10} ) = \frac{38}{7} = 5 \frac{3}{7} [/tex]
