Question

numerator is 2 less than denominator of a rational number and when 1 is subtracted from numerator and denominator both, the rational number in its simplest form is ½ . What is the rational number? (pls give the right answer 3)

Answer 1

Answer:

3/5

Step-by-step explanation:

Let the denominator be x

Numerator = x-2

Rational no. = x-2/x

A.T.Q

x-2-1/x-1 = 1/2

x-3/x-1 = 1/2

2(x-3) = 1( x-1)

2x - 6 = x -1

2x-x = -1 +6

x = 5

Rational no. = 5-2/5 = 3/5
