=2/5 x ( 2x 4 +3 /4 - 13 /12)
=2/5 ×( 11/4 -13/12)
=2/5 × ( 11 / 4 amplificat cu 3 - 13/12)
= 2/5 × (11 ×3 /4×3 -13/12
=2/5× (33/12 -13/12)
=2/5× 20/12
[tex] \frac{2}{5 } | \times \frac{20}{12} [/tex]
12si 2 se sinplifica cu 2 , iar 20 si 5 cu 5
2,si 12 :2 , 20 si5 :5
= 1/1 ×4/6
= 4 /6
Sper ca te-am ajutat!
