Question

The product of two rational numbers is -6/7 . if one
of the numbers is-8/5 find the other.​

Answer 1

Given

$\bold{Product \ of \ 2 \ rational \ numbers} = \dfrac{-6}{7}$

$\bold{One \ of \ the \ number} = \dfrac{-8}{5}$

Let the other number be x

$\dfrac{-8}{5} x = \dfrac{-6}{7}$

$\implies x = \dfrac{-6}{7} * \dfrac{5}{-8}$

$\implies x = \dfrac{15}{28}$

$\boxed{\boxed{\bold{Therefore, \ the \ other \ number \ is \ \frac{15}{28}}}}}$

Answer:

I am telling you answer you have to make it brainliest

Step-by-step explanation:

GIVEN:

Product of two rational numbers is -6/7

that means

x ×y = -6/7

if x is -8/5

then , -8/5 × y = -6/7

y= -6/7× -5/8

y = 30/56 or 15/28
