Question

the product of two rational number is -16/21 if one of them is -2/9 find the other

Answer 1

Hey

Here is your answer

Given that,

Product of two numbers = -16/21
One number = -2/9
Another number = ?

Let the unknown number be x.

X x (-2/9) = (-16/21)
X = (-16/21) x (-9/2)
X = 8 x 3/7
X = 24/7

Hope it helps you!

Answer 2

Here is your answer


suppose other rational number is y.


a/q,

-2/9 × y = -16/21


-2y = -16×9/21

y = (-16×9/21 × -2 )


Y = 8×3/7 = 24/7.


Other rational number = y = 24/7.

Hope it helps you ^_^
