If the numerator and denominator of a proper fraction are increased by the same positive quantity which is greater than zero, the resulting fraction is
always less than the original fraction
always greater than the original fraction
always equal to the original fraction
such that nothing can be claimed definitely
Answer is (d). We can apply the fundamental property of ratios: when the numerator is less than the denominator, adding the same positive quantity to both the numerator and denominator results in a fraction greater than the original one. a/b<(a+x)/(b+x) . But in above case we do not whether the fraction is positive or negative. If it is positive, then the answer will be different from when it will be negative. Hence we can't say anything.
