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!
