**Question 1.**

The numerator of a fraction is 4 less than the denominator. If the numerator is decreased by 2 and denominator is increased by 1, then the denominator is eight times the numerator. Find the fraction. **(C.B.S.E. 1990)**

**Solution:**

Let numerator of a fraction = x

and denominator = y

Then fraction =

According to the conditions,

y – x = 4 ….(i)

and 8 (x – 2) = y + 1

=> 8x – 16 – y + 1

=> 8x – y = 1 + 16

=> 8x – y= 17 ….(ii)

Adding (i) and (ii)

7x = 21 => x = 3

y – 3 = 4

=> y = 4 + 3 = 7

Hence fraction =

**Question 2.**

A fraction becomes if 2 is added to both numerator and the denominator. If 3 is added to both the numerator and the denominator, it becomes . Find the fraction.** (C.B.S.E. 1990)**

**Solution:**

Let the numerator of a fraction = x

and denominator = y

Fraction = =

**Question 3.**

A fraction becomes if 1 is subtracted from both its numerator and denominator. If 1 is added to both the numerator and denominator, it becomes . Find the fraction. **(C.B.S.E. 1993C)**

**Solution:**

Let the numerator of a fraction = x

and denominator = y

**Question 4.**

If we add 1 to the numerator and subtract 1 from the denominator, a fraction becomes 1. It also becomes if we only add 1 to the denominator. What is the fraction.

**Solution:**

Let numerator of a fraction = x

and denominator = y

**Question 5.**

The sum of the numerator and denominator of a fraction is 12. If the denominator is increased by 3, the fraction becomes . Find the fraction. **(C.B.S.E. 2006C)**

**Solution:**

Let the numerator of a fraction = x

and denominator = y

Fraction = =

**Question 6.**

When 3 is added to the denominator and 2 is subtracted from the numerator a fraction becomes . And, when 6 is added to numerator and the denominator is multiplied by 3, it becomes . Find the fraction.

**Solution:**

Let numerator of a fraction = x

and denominator = y

**Question 7.**

The sum of a numerator and denominator of a fraction is 18. If the denominator is increased by 2, the fraction reduces to . Find the fraction. **(C.B.S.E. 1997C)**

**Solution:**

Let the numerator of a fractrion = x

and denominator = y

**Question 8.**

If 2 is added to the numerator of a fraction, it reduces to and if 1 is subtracted from the denominator, it 1 reduces to . Find the fraction. **(C.B.S.E. 1997C)**

**Solution:**

Let the numerator of a fraction = x

and denominator = y

**Question 9.**

The sum of the numerator and denominator of a fraction is 4 more than twice the numerator. If the numerator and denominator are increased by 3, they are in the ratio 2 : 3. Determine the fraction **(C.B.S.E. 2001C)**

**Solution:**

Let the numerator of a fraction = x

and denominator = y

**Question 10.**

If the numerator of a fraction is multiplied by 2 and the denominator is reduced by 5 the fraction becomes . And, if the denominator is doubled and the numerator is increased by 8, the fraction becomes . Find the fraction.

**Solution:**

Let the numerator of fraction = x

and denominator = y

**Question 11.**

The sum of the numerator and denominator of a fraction is 3 less than twice the denominator. If the numerator and denominator are decreased by 1, the numerator becomes half the denominator. Determine the fraction. **(C.B.S.E. 2001C)**

**Solution:**

Let the numerator of a fraction = x

and denominator = y

Then fraction =

According to the conditions given,

x + y = 2y – 3

=> x + y – 2y = -3
