Question

The denominator of a rational number is 4 more than its numerator. If 11 is added to the number and 1 is subtracted from the denominator, the new number is 7 by 3. Find the original number.

Answer 1

Answer:

The original number=3/7

Step-by-step explanation:

Lets suppose that x is the numerator. Then,

Original number= x/4+x

Then, 11 is added and 1 is subtracted. So,

x+11/4+x-1=7/3

x+11/3+x=7/3

Cross multiply. Then,

21+7x=33+3x

7x-3x=33-21

4x=12

x=12/4

x=3.

Original number= x/4+x

                        =3/4+3

                        =3/7.
