Question
Evaluate the following expressions for x = -2, y = -1, z = 3:
$\frac{\text{x}}{\text{y}}+\frac{\text{y}}{\text{z}}+\frac{\text{z}}{\text{x}}$
$\frac{\text{x}}{\text{y}}+\frac{\text{y}}{\text{z}}+\frac{\text{z}}{\text{x}}$
✓
Answer
$\frac{\text{x}}{\text{y}}+\frac{\text{y}}{\text{z}}+\frac{\text{z}}{\text{x}}$$=\frac{-2}{-1}+\frac{-1}{3}+\frac{3}{-2}$
$=\frac{12-2-9}{6}=\frac{1}{6}$
$=\frac{12-2-9}{6}=\frac{1}{6}$
