(c) 1
(d) 2​

Answer 1

Step-by-step explanation:

<b>

Let the denominator = x

Numerator = x - 6

Original fraction = ( x - 6 ) / x ---(a)

Follow the question as per as

( x - 6 + 3 ) / x = 2/3

( x - 3 ) / x = 2 / 3

3( x - 3 ) = 2x

3x - 9 = 2x

3x - 2x = 9

x = 9

ACCORDING TO THE QUESTION;

Original/Required fraction = ( x - 6 ) / x

= ( 9 - 6 ) / 9

= 3 / 9

ANS:- 3/9
