Question

the product of 2 rational numbers is -28/81. if one of the number is 14/27 find the other

Answer 1

Answer:

$x = \frac{-2}{3}$

Step-by-step explanation:

$\frac{14}{27} * x = \frac{-28}{81}$

$x = \frac{-28}{81} / \frac{14}{27}$

$x = \frac{-28}{81} * \frac{27}{14}$

$x = \frac{-2}{3} * \frac{1}{1}$   (After cancellation)

$x = \frac{-2}{3}$
