Question

{[(- $\frac{5}{12}$ )+(- $\frac{1}{18}$ )}+[(- $\frac{4}{9}$ ) - ( + $\frac{1}{6}$ )]} x ( -2 $\frac{10}{13}$ ) ajutatimaaa va rog dau coroana la primul raspuns

Answer 1

={[(-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)=

=3
