The denominator of a rational number is less its numerater than 5. IF 5 is added to
the numerator the new number becomes 11/6. Find the original rational number
Answers
Answer:-
D = N - 5
(N + 5)/D = 11/6
(N + 5)/(N - 5) = 11/6
6N + 30 = 11N - 55
5N = 85
N = 17
D = 12

Answer:
let the rational number be 'x' .
........
Step-by-step explanation:
denominator of rational number = x-5
numerator of rational number = x+5
now,
5 is added to the numerator ,
the new number becomes 11/6
according to the question,
x+5/x-5=11/6
6(x+5)=11(x-5)
6x-11x= -55x-30
-5x = -85
x= 85/5
x= 17
now put the value of 'x' in denominator and numerator.
the original rational number= x+5/x-5
= 17+5/17-5
= 22/12is the answer.
