Question

What is the product of $\frac{-19}{29}$ and its multiplicative inverse?

• A. $\frac{29}{-19}$
• B. $\frac{19}{29}$
• C. 1
• D. 0

Answer 1

The correct option is C 1

The product of any number and its multiplicative inverse is always 1.

The multiplicative inverse of $\frac{-19}{29}$ is $\frac{29}{-19}$.
So, product of $\frac{-19}{29}$ and $\frac{29}{-19}$
$=\frac{-19}{29}\times \frac{29}{-19}=1$

Hence, option b is correct.
