[tex] \frac{2}{3} - \frac{2}{3} \times ( - \frac{9}{2}) = \frac{2}{3} - \frac{2 \times - 9}{3 \times 2} = \frac{2}{3} - \frac{ - 18}{6} = \frac{2}{3} - ( - \frac{18}{6}) = \frac{2}{3} - ( - 3) = \frac{2}{3} + 3 = \frac{11}{3} [/tex]
2 / 3 - 2 / 3 x ( - 9 / 2 ) = 11 / 3
= 2 / 3 - ( 2 / 2 ) x ( - 9 / 3 ) =
= 2 / 3 + 3 =
= 2 / 3 + 9 / 3 =
= 11 / 3
= 3 intregi si 2 / 3 =3,(6)
