Question

2. Evaluate each of the following expressions for x = -2, y = -1, z = 3: ) (x/y) + (y/z) + (z/x)​

Answer 1

Answer:

The answer is 1/6

Step-by-step explanation:

Given,
X = -2
Y = -1
Z = 3
Given Expression : $\frac{x}{y} + \frac{y}{z} + \frac{z}{x}$
⇒ $\frac{-2}{-1} +\frac{-1}{3} + \frac{3}{-2}$
⇒ $\frac{2}{1} +\frac{-1}{3} +\frac{-3}{2}$
⇒ $\frac{2 *6}{1*6} + \frac{-1 *2}{ 3*2} + \frac{-3 *3}{2*3}$ =
⇒  $\frac{12}{6} -\frac{2}{6} -\frac{9}{6}$ = $\frac{1}{6}$
∴The answer for the given expression  is $\frac{1}{6}$

Hope this helps!
