Answer 2

Answer:

2/5, 6/9

Step-by-step explanation:

Let the denominator be x.

Then the numerator = x - 3.

Original fraction = (x - 3/x).

Now,

Given that 1 is added to numerator, fraction is decreased by 1/15.

⇒ (x - 3/x + 1) = (x - 3/x) - 1/15

⇒ (x - 3/x) + (x - 3/x + 1) = 1/15

⇒ (x - 3)(x + 1) - x(x - 3)/x(x + 1) = 1/15

⇒ x² - 2x - 3 - x² + 3x/x² + x = 1/15

⇒ x - 3/x² + x = 1/15

⇒ x² + x = 15x - 45

⇒ x² - 14x + 45 = 0

⇒ x² - 9x - 5x + 45 = 0

⇒ x(x - 9) - 5(x - 9) = 0

⇒ x = 5,9

When x = 5:

Original fraction = (5 - 3)/5 = 2/5.

When x = 9:

Original fraction = (9 - 3)/9 = 6/9.

Therefore:

Required fraction = 2/5 (or) 6/9.

Hope it helps!
