Question

The sum of numerator & denominator of a fraction is 13. If 3 is added to numerator

& 5 to denominator, the fraction becomes 1/2. Find the fraction​

Answer 1

Answer:

let the numerator be x and denominator be y

then, numerator= 3+X

denominator=5+y

according to the question,

3+X/5+y=1/2

5+y=1/2*3+X

5+y=3/2+X

5-3/2=x-y

7/2=x-y

now,

numerator-denominator=7/2

3+7-5+2=7/2

7/2-3=1/2

therefore,the required fraction=7/2
