va rog ajuta ti ma!!! dau 50 de puncte​

Answer 1

Răspuns:

5/9  

Explicație pas cu pas:

[1/3+1/3:(³⁾1-1/3)]:3/2 =

= [1/3+1/3:(3-1)/3]:3/2 =

= [1/3+1/3: 2/3]·2/3 =

= [1/3+1/3 ·3/2] · 2/3 =

= (²⁾1/3 + 3/6) ·2/3 =

= [(2+3)/6]·2/3 =

= 5/6 ·2/3 = 10/18⁽² =

= 5/9  

Answer 2

Explicație pas cu pas:

$\Big[ \dfrac{1}{3} + \dfrac{1}{3} : \Big(^{3)} 1 - \dfrac{1}{3} \Big)\Big] : \dfrac{3}{2} = \Big( \dfrac{1}{3} + \dfrac{1}{3} : \dfrac{3 - 1}{3} \Big) \cdot \dfrac{2}{3} = \Big( \dfrac{1}{3} + \dfrac{1}{3} : \dfrac{2}{3} \Big) \cdot \dfrac{2}{3} = \Big( \dfrac{1}{3} + \dfrac{1}{ \not3} \cdot \dfrac{ \not3}{2} \Big) \cdot \dfrac{2}{3} = \Big( \dfrac{^{2)} 1}{3} + \dfrac{^{3)}1}{2} \Big) \cdot \dfrac{2}{3} = \dfrac{2 + 3}{6} \cdot \dfrac{2}{3} = \dfrac{5}{ \not6} \cdot \dfrac{ \not2}{3} = \dfrac{5}{3} \cdot \dfrac{1}{3} = \bf \dfrac{5}{9}$
