Question

The product of two rational numbers is $-\frac{14}{27}.$ If one of the numbers be $\frac{7}{9},$ find the other.

Answer 1

It is given that$,$

Product of two rational numbers $=$$-\frac{14}{27}.$

One number $=$$\frac{7}{9},$

We have to determine the other number

Let us assume the other number be $x.$

According to given details we get to know that

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

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

$x=-\frac{2}{3}\times \frac{1}{1}$

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

Hence$,$ the other number is $-\frac{2}{3}$
