Corrected Question:
- The denominator of a rational number is greater than its numerator by 3 If numerator and denominator are increased by 1 and 4 respectively the number obtained is ½. Find the rational number.
⠀⠀⠀⠀⠀
❍ Let the numerator of the fraction be x respectively. Then, it's denominator becomes (x + 3).
⠀⠀⠀⠀⠀
⠀⠀⠀⠀⠀
- If the numerator and denominator of the fraction are increased by 1 and 4 respectively. The number obtained is ½.
⠀⠀⠀⠀⠀
Therefore,
⠀⠀⠀⠀⠀
⠀⠀⠀⠀⠀
Hence,
- Numerator of the fraction is x = 5.
- Denominator of the fraction is (x + 3) = (5 + 3) = 8.
⠀⠀⠀⠀⠀
