− 5 12 -\frac{5}{12} − 1 2 5

Translate the phrase to a numerical expression, then evaluate the expression: the sum of the reciprocal of two and the opposite of three.

1 2 + ( − 3 ) = − 5 2 \frac{1}{2}+\left(-3\right)=-\frac{5}{2} 2 1 + ( − 3 ) = − 2 5

− 1 2 + 3 = 5 2 -\frac{1}{2}+3=\frac{5}{2} − 2 1 + 3 = 2 5

1 2 + ( − 3 ) = 5 2 \frac{1}{2}+\left(-3\right)=\frac{5}{2} 2 1 + ( − 3 ) = 2 5

− 1 2 + 3 = − 5 2 -\frac{1}{2}+3=-\frac{5}{2} − 2 1 + 3 = − 2 5
