Answer 1

The rational number can be any fraction where numerator is 3 less than denominator like 1/4 or 2/5 or 3/6 or 4/7.

1) According to the first statement, numerator is 3 less than the denominator of the rational number.

Let denominator be x, then numerator would be x-3.

2) Hence the rational number would be x-3/x

3) According to the second statement, adding 3 to numerator makes the fraction 1.

x-3+3/x = 1  or x/x = 1

4) This type of relation is true for any value of x, Hence x can be any real number.
