Answer: The answer in 19/8
Explanation: According to the question, the information we have is-
Product = 19/6
One Number= 4/1/3
= 4/1 \× 1/3
= 4/3
Let the other number be 'X'
So, X * 4/3 = 19/8
X = 19/8 × 3/4
(The number is reciprocated when it goes on another side)
Hence, X = 19/8
Rechecking: 19/8 × 4/3
= 19/6
Hence proved.
