Question

the product of two rational numbers is -25 upon 49 . if one of the numbers is 5 upon 8 , find the other ?​

Answer 1

Let's

Unknown Rational Number = 'x'

Given,

Sum of two Rational Numbers = $\frac {-25}{49}$

Other Rational Number = $\frac {5}{8}$

According To The Sum.

➝ $\Large {x × \frac {5}{8} = \frac {-25}{49}}$

➝ $\Large {x = \frac {-25}{49}×\frac {8}{5}}$

➝ $\Large {x = \frac {-5×8}{49}}$

➝ $\Large {x = \frac {-40}{49}}$

Therefore,

The other Rational Number is $\boxed{\frac {-40}{49}}$
