Let the numerator = xthen the denominator = x+2Now, according to question,xx+2+3 = 12⇒xx+5 = 12⇒2x = x + 5⇒2x - x = 5⇒x = 5Now, numerator = x  = 5denominator = x+2 = 5+2 = 7Original fraction = 57

The denominator of a rational number is 2 more than the numerator. if 3 is added to the denominator, the number obtained is 1/2 . Find the number and please answer this question using one variable only.
