Answer:-
Let the fraction be x/y.
Given :
Numerator is 1 less than the denominator.
→ x = y - 1 -- equation (1)
And,
If the numerator is decreased by 2 and denominator is increased by 3 the fraction becomes 1/4.
According to the question,
→ (x - 2)/(y + 3) = 1/4
Substitute the value of x from equation (1)
→ (y - 1 - 2)/y + 3 = 1/4
→ (y - 3)/(y + 3) = 1/4
After cross multiplication we get,
→ 4(y - 3) = y + 3
→ 4y - 12 = y + 3
→ 4y - y = 3 + 12
→ 3y = 15
→ y = 5
Substitute "y" value in equation (1).
→ x = y - 1
→ x = 5 - 1
→ x = 4
Hence, the fraction x/y is 4/5.
