Given:
- The denominator of a rational number is greater than its numerator by 8
- If the numerator is increased by 17 and the denominator is decreased by 1 the number obtained is 3/2
To find:
Find the rational number
Solution:
Suppose numerator of the rational number is 'P' then denominator is P + 8
Rational number is
Numerator is increased by 17 , then it becomes P + 17
Denominator is decreased by 1 , then it becomes P + 8 - 1 = P + 7
Now,
New rational number is
⠀
⠀
⠀
⠀⠀
⠀⠀
⠀
Thus, numerator is 13
Denominator is = P + 8 = 13 + 8 = 21
⠀
Therefore,
