1. Given :

   The product of two rational numbers is 15/4. Also, one of them is 3/9.

   To find :

   We have to find the another number.

   Solution :

   Let the unknown rational number be z.

   Now, according to the question :

   z × (3/9) = 15/4

   z = 15/4 ÷ 3/9

   z = 15/4 × 9/3

   z = 45/4

   Therefore, the other rational number is 45/4.

   Verification :

   Now, let’s verify whether 45/4 is the right solution or not :

   z × (3/9) = 15/4

   (45/4) × (3/9) = 15/4

   15/4 = 15/4

   LHS = RHS

   Hence, verified!
