Question

rezultatul calculului 2 pe 3-2pe 3ori(-9pe 2) este egal cu?

Answer 1

$\frac{2}{3} - \frac{2}{3} \times ( - \frac{9}{2}) = \frac{2}{3} - \frac{2 \times - 9}{3 \times 2} = \frac{2}{3} - \frac{ - 18}{6} = \frac{2}{3} - ( - \frac{18}{6}) = \frac{2}{3} - ( - 3) = \frac{2}{3} + 3 = \frac{11}{3}$

Answer 2

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)
