Question

By what rational number should - 8/39 be multiplied to obtain 5/26

Answer 1

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 = 5/26

x = 5/26 × 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

let the no. be x
