Question

In the equation $z=\frac{x}{y}$ , find the value of z when x = -10 and y = -20

• A. $z=\frac{1}{2}$​​​​​​
• B. $z=\frac{9}{16}$​​​​​​
• C. $z=\frac{3}{7}$​​​​​​
• D. $z=\frac{2}{7}$​​​​​​

Answer 1

The correct option is A

$z=\frac{1}{2}$​​​​​​

$z=\frac{x}{y}$

x = -10 and y = -20

$z=\frac{-10}{-20}$

$z=\frac{-1}{-2}$

$z=\frac{1}{2}$​​​​​​

$z=\frac{1}{2}$​​​​​​
