Question

the numerator of fraction is 4 less than the denomenator .if 1 is added To both its numerator and denomenator ,it becomes 1/ 2 .find the friction​

Answer 1

Answer:

Let the fraction be a/b

Numerator= denominator-4

a=b−4⇒b−a=4

If 1 added to both numerator and denomator then fraction =

2/1

b+1/a+1

=2/1

2a+2=b+1

2a−b=−1

(2a−b)+(b−a)=4−1

a=3,b=7

Fraction= 7/3
