A fraction become
Answer :
Let the numerator be ‘a’ and denominator be ‘b’
Given, fraction becomes 1/3 if 1 is subtracted from both its numerator and denominator. If 1 is added to both the numerator and denominator, it becomes 1/2.
⇒ 3a – 3 = b – 1
⇒ b = 3a – 2 ------ (1)
Also, if 1 is added to both the numerator and denominator, it becomes 1/2.
⇒ b = 2a + 1 ---------- (2)
Equating (1) and (2)
⇒ 3a – 2 = 2a + 1
⇒ a = 3
Thus, b = 7
Fraction is 3/7
