Answer 1

Hey User!!!

according to the question, the product of two rational numbers is 47/40

we are given one of them, that is -13/5

let the another rational number be x.

therefore x * -13/5 = 47/40

>> x = 47/40 * 5/-13

>> x = 47/8 * 1/-13

>> x = -47/104

verification :-

= -47/104 * -13/5

= 611/520 (divide both numerator and denominator by 13)

= 47/40

hence verified.

and the another rational number is -47/104.

Cheers!!!
