Question

The product of two rational numbers is -14/27 if one of the number is 7/9 find the other

Answer 1

Let the other number be x

According to the question

$x \times \frac{7}{9} = \frac{ - 14}{27} \\ x = \frac{ - 14}{27} \div \frac{7}{9} \\ x = \frac{ - 14}{27} \times \frac{9}{7} \\ x = \frac{ - 2}{3}$
