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)

**Answer
1** :

Let numerator of a fraction = x

and denominator = y

Then fraction = x/y

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 = x/y

**Answer
2** :

Let the numerator of a fraction = x

and denominator = y

Fraction = x/y = 7/9

**Answer
3** :

Let the numerator of a fraction = x

and denominator = y

**Answer
4** :

Let numerator of a fraction = x

and denominator = y

**Answer
5** :

Let the numerator of a fraction = x

and denominator = y

Fraction= x/y = 5/7

**Answer
6** :

Let numerator of a fraction = x

and denominator = y

**Answer
7** :
