Question

The product of two rational numbers is -78 . If one of numbers is 514, find the other number.​

Answer 1

Answer:

-39/257

Step-by-step explanation:

Let the two numbers be x and y.

xy= -78

Put the value of x(514).

514y= -78

y= -78/514

y= -39/257 is the required value.

Answer 2

$\frac{-39}{257}$ is the other number.

We know that the given details,

The product of two rational numbers = −78

One rational number = 514

Let us consider the other number as x

Now, solving

514 x X = -78

514X = -78

​X =  $\frac{-78}{514}$

X =  $\frac{-39}{257}$ = 0.1517

∴ the other rational number is  $\frac{-39}{257}$
