-3/19-(3/4-22/19)-1/4

Answer 1

\(-\dfrac{3}{19}-\dfrac{3}{4}+\dfrac{22}{19}-\dfrac{1}{4}=\left(-\dfrac{3}{19}+\dfrac{22}{19}\right)+\left(-\dfrac{3}{4}-\dfrac{1}{4}\right)=\dfrac{19}{19}-\dfrac{4}{4}=1-1=0\)

Answer 2

-3/19-(3/4-22/19)-1/4

=-3/19-(57/76-88/76)-1/4

=-3/19-(-31/76)-1/4

=-12/76-(-31/76)-1/4

=19/76-1/4

=19/76-19/76

=0

 

 

Answer 3

-3/19-(3/4-22/19)-1/4

=1+(-1)

=0
