{[(- [tex] \frac{5}{12} [/tex] )+(- [tex] \frac{1}{18} [/tex] )}+[(- [tex] \frac{4}{9} [/tex] ) - ( + [tex] \frac{1}{6} [/tex] )]} x ( -2 [tex] \frac{10}{13} [/tex] ) va rog ajutatimaaaa

Răspuns :

={[(-15/36)-(2/36)]+[(-8/18)-(3/18)]}x(-36/13)=

=[(-17/36)-(11/18)]x(-36/13)=

=(-17/36-22/36)x(-36/13)=

=(-39/36)x(-36/13)=

=(39x36)/(36x13)=
