Question

by what rational number should (-8)/(39) be multiplied to obtain (5)/(26)​

Answer 1

Answer:

Given,

The main number = - 8/39

The final result = 5/26

To find,

The rational number which we need to multiply with the main number.

Solution,

Let,the rational number = x

[Assume, x as a variable to do the further mathematical calculations.]

Now, according to the data mentioned in the question

- 8/39 x x = 5/26

x = 5/26 x 39/-8

x = -195/208

X = -15/16

(The result of multiplication of two negative numbers will be a positive number, so it's satisfy the criteria mentioned in the question.)

Hence,the rational number is -15/16.

Answer 2

Answer:

-15/16

Mark me as a brainlist

Step-by-step explanation:

let the Rational number be y .

-8/39 x y = 5/26

y= 5/26 x 39/-8

y= 195/-208

y=15/-16

y= -15/16
