Hey
Let two numbers be x and y .
Now ,
product of these numbers :-
x * y = 2025 ––– ( i )
quotient of these numbers :-
x / y = 9 / 5
=> x = 9y / 5 .
Now putting the value if x in eq ( i )
x * y = 2025
=> 9y / 5 * y = 2025
=> 9y² = 2025 * 5
=> y² = 225 * 5
=> y = √ 225 * 5
=> y = 15 √5 .
So,
x = 9 * y / 5
x = 9 * 15 √5 / 5
x = 9 * 3 √5
x = 27√5

Let one of the numbers be x. Product is 2025
Other number is 2025 / x
x * 2025 / x = 2025
Therefore
x/2025 / x = 9/5
x^2 / 2025 = 9/5
x^2 / (45)^2 = 9/5
5x = 45 * 9
x = 405 / 5
x = 81
2025 / 81 = 25
Other number is 25
Other number is 2025 / x
x * 2025 / x = 2025
Therefore
x/2025 / x = 9/5
x^2 / 2025 = 9/5
x^2 / (45)^2 = 9/5
5x = 45 * 9
x = 405 / 5
x = 81
2025 / 81 = 25
Other number is 25
