Question

The denominator of a rational number is greater than its numerator by 4. If 3 is subtract from the numerator and 4 added to the denominator , the new number become 2/13 . Find the original number ​

Answer 1

Answer:

Original number=5/9

Step-by-step explanation:

Numerator=x

Denominator=x+4

(x-3)/(x+8) = 2/13

=> x=5

Answer 2

Answer:

original number=5/9

Step-by-step explanation:

acc to question,

x/x+4 ---------->(original number)(1)

acc to given condition,

x-3/x+4+4=2/13

13(x-3)=2(x+8)---------->(on cross multiplication)

13x-39=2x+16

13x-2x=16+39

11x=55

∴x=55/11

 x=5

put x=s in eq(1),

5/5+4

=5/9= original number
