A fraction becomes equal to 4/5 if 1 is added both numerator and denominator. If however 5 is substracted from both numerator and denominator the fraction becomes equal to 1/2. What is the fraction. |
|
Answer» Answer: Step-by-step explanation:
To Find,
Solution, Let the fraction be x/y. Then, According to the QUESTION, x + 1/y + 1 = 4/5 And, x - 5/y - 5 = 1/2 ⇒ 5x + 5 = 4y and 2x - 10 = y - 5 ⇒ 5x - 4y + 1 = 0 and 2x - y - 5 = 0 By using cross-multiplication, we have ⇒ x/- 4 × (- 5) - (- 1) × 1 = - y/5 × (- 5) - 2 × 1 = 1/5 × (- 1) - 2 × (- 4) ⇒ x/20 + 1 = y/25 + 2 = 1/- 5 + 8 ⇒ x/21 = y/27 = 1/3 ⇒ x = 21/3 = 7 ⇒ y = 27/3 = 9 Hence, the required fraction is 7/9. |
