Let the numerator be x.
Therefore, denominator will be 18-x.
According to question , If the denominator is increased by two , the new fraction is 1/3.→
x /((18-x)+2) = 1/3
or, x/(20-x) = 1/3
or, 3x = 20-x
or, 3x + x = 20
or, 4x = 20
or, x = 20/4
or, x = 5
Therefore , numerator is 5.
Denominator = 18-5 = 13
Out fraction = 5/13
Answer → The Fraction is 5/13

Answer:5/13
Step-by-step explanation:
Let the fraction be x/y, where x=numerator and y = denominator
X+y=18------(1)
X/y+2=1/3
Y+2=3x
3x-y=2-------(2)
3x-y=2
X+y=18
4x=20
X=5
5+y=18
Y=13
X/y=5/13
