Answer:
7/10
Step-by-step explanation:
Given that the denominator of a fraction is 3 more than the numerator. Let's say that the numerator is x then denominator is 3 more than numerator i.e. (x + 3).
Also given that, if 5 is added to both numerator and denominator, then fraction becomes 4/5. Now,
- Numerator = (x + 5)
- Denominator = (x + 3 + 5) = (x + 8)
As per given statement,
→ (x + 5)/(x + 8) = 4/5
Cross multiply them,
→ 5(x + 5) = 4(x + 8)
→ 5x + 25 = 4x + 32
→ 5x - 4x = 32 - 25
→ x = 7
Therefore, the numerator is x i.e. 7 and denominator is (x + 3) i.e. (7 + 3) = 10.
Hence, the fraction is Numerator/Denominator = 7/10.
