Heya !!!
Let numerator and denominator of fraction be. and Y.
According to the question,
Numerator + Denominator = 11
X + Y = 11 --------(1)
Fraction = Numerator/Denominator = X/Y
X + 1 / Y - 2 = 2/3
3 ( X + 1 ) = 2 ( Y - 2 )
3X + 3 = 2Y - 4
3X - 2Y = -4-3
3X - 2Y = -7 -------(2)
From equation (1) we get,
X + Y = 11
X = ( 11 - Y ) ------(3)
Putting the of X in equation (2).
3X - 2Y = -7
3 × ( 11 - Y ) - 2Y = -7
33 - 3Y - 2Y = -7
-5Y = -7-33
-5Y = -40
Y = -40/-5 = 8
Putting the value of Y in equation (3)
X = 11 - Y = 11-8 = 3
Numerator = X = 3
And,
Denominator = Y = 8
Fraction = Numerator/Denominator = 3/8.
