Answer 1

Răspuns:

107/15

Explicație pas cu pas:

3-2(-12/5+1/3)=

3-2(-36/15+5/15)=

3-2*(-31/15)=

3+62/15=

45/15+62/15=107/15

Answer 2

Răspuns:

$= \frac{107}{15}$

Explicație pas cu pas:

$3 - 2 \cdot \Big[- \frac{12}{5} + 0,(3)\Big]$

$= 3 - 2 \cdot \Big( - \frac{12}{5} + \frac{3 {}^{(3} }{9} \Big)$

$= 3 - 2 \cdot \Big( - \frac{ {}^{3)} 12}{5} + \frac{ {}^{5)} 1}{3} \Big)$

$= 3 - 2 \cdot \Big( - \frac{36}{15} + \frac{5}{15} \Big)$

$= 3 - 2 \cdot \Big( - \frac{31}{15} \Big)$

$= {}^{15)} 3 + \frac{62}{15} = \frac{45}{15} + \frac{62}{15} = \boxed{ \frac{107}{15} }$
