Question

the denominator of a fraction is 4 more than its numerator . on subtracting 1 from each numberator and the denominator the fraction becomes 1/2. find the original fashion
​

Answer 1

Answer:

Let numerator be x.

Then,denominator be 4+x

x-1/4+x=1/2

2(x-1)=1(x+4)

2x-2=x+4

2x-x=4+2

x=6

Hence,the numerator=6

And denominator 4+x=4+6=10

fraction=6/10=3/5

Hence,original fraction is 3/5

Answer 2

Answer:

x=4

Explanation:

according to condition

x-1/x+4-1 = 1/2

2x-1 = x+3

x=4.
