Answer:

Original number = 13 / 11

Explanation:

Assume:

Numerator of a rational number = x

So,

Denominator of a rational number = x - 2

Rational number  = \frac{x}{x-2}

Numerator decreased by 5 the denominator is increased by 1

New Rational number = 2/3

So,

\frac{x-5}{x-2+1}=\frac{2}{3}\\\\\frac{x-5}{x-1} = \frac{2}{3}\\\\x=13

So,

Numerator of a rational number = 13

Denominator of a rational number = 13 - 2

Denominator of a rational number = 11

Original number = 13 / 11
