Question

If 1 is added to both numerator and denominator of a certain fraction it becomes 1 upon 2 if 1 is subtracted from numerator and 3 is added to the denominator the fraction becomes 1 upon 3 then find the fraction

Answer 1

Answer:

let numerator be x and denominator be y

then x+1/y+1 = 1/2 after cross multiplication and simplify we get y-2x=1

next condition

x-1/y+3=1/3

after simplification

3x-6=y

substitute y in 1st equation

Step-by-step explanation:

we get x=7 and then y=15

hence number is 7/15
