Question

Efectuați: b)(-3)×1/4×(-2/3)-0,(3)×(-1,25)=​

Answer 1

Răspuns:

$= \frac{11}{12}$

Explicație pas cu pas:

$( - 3) \times \frac{1}{4} \times ( - \frac{2}{3} ) - 0.(3) \times ( - 1.25) =$

$( - 3) \times \frac{1}{4} \times ( - \frac{2}{3} ) - \frac{3}{9} \times ( - 1.25) =$

$= \frac{1}{2} - \frac{3}{9} \times ( - \frac{5}{4} ) \\ \: \: \: \: \: \: \: \: \: = \frac{1}{2} + \frac{5}{12} = \frac{6}{12} + \frac{5}{12} = \boxed{\frac{11}{12} }$
