Question

the product of two rational numbers is -14/27. if one of the numbers be 7/9, find the other.​

Answer 1

Step-by-step explanation:

Let us assume the other number be y.

Given, product of two rational number = -14/27

One number = 7/9

Then, = y × (7/9)= -14/27

= y = (-14/27)/ (7/9)

= y = (-14/27) × (9/7)

= y = (-2/3) × (1/1)

= y = -2/3

So, the other number is -2/3.

Answer 2

Here is your answer

Let the other number be x

(If one no is 7/9 than other will be x)

Product of both numbers = -14/27

= 7 × x = -14

9. 27

= x = -14 ÷ 7

27. 9

=. x. = -14 × 9

27. 7

( Reduce 14 by 2 , 7 by 1 , 27 by 3 and 9 by 1 )

=. x. = 2
