Answer 2

Answer:

Other rational number is $\frac{15}{16}$ .

Step-by-step explanation:

Given -

The product of two rational numbers is $\frac{-5}{8}$

One of the number is $\frac{-2}{3}$ .

To find -

Other rational number

Solution -

Let, x be the other rational number .

As per the given information ,

$x \times \frac{(-2)}{3} = \frac{(-5)}{8}$

When fraction is shift from one side to other it get inverse.

$x = \frac{(-5)}{8} \times \frac{3}{(-2)}$

$x= \frac{(-5)\times 3}{8\times (-2)}$

$x= \frac{-15}{-16}$

Negative sign is present in both numerator and denominator it get cut .

$x =\frac{15}{16}$

∴ Other rational number is $\frac{15}{16}$ .
