Let the other rational no. be ‘x’

Product is given i.e., 35/117

and

one no. is 3/13

therefore,

3/13 × x = 35/117

x = 35/117 × 13/3

=> 35/27

hope this helps u

Answer:

Let the unknown no. be 'x'

A.T.Q

(3/13)x = 35/117

or, x= (35/117) × (13/3)

or, x= 455/351

or, x= 35/27

Therefore, the unknown no. is 35/27
