Question

(ii) The denominator of a fraction is greater than the numerator by 3. If 7 is added to the
numerator, the fraction increases by unity. Find the fraction.


​

Answer 1

Answer:

4/7

Step-by-step explanation:

Let the numerator be x and the denominator be y.

Then ATQ,

x + 3 = y

x + 7 / y = x / y +1

x + 7 / y = x + y / y

x + 7 = x + y                                                           (y is cancelled from both sides)

7 = y

x = 4
