A rational number is a number of the form p/q where p and q are integers and q > 0.If p/q and r/s are two rational numbers thenp/q + r/s = (p*s + q*r) / (q*r)andp/q - r/s = (p*s - q*r) / (q*r)The answers may need simplification.

If a is rational then there exist integers p and q such that a = p/q where q>0. Similarly, b = r/s for some integers r and s (s>0) Then a*b = p/q * r/s = (p*r)/(q*s) Now, since p, q r and s are integers, p*r and q*s are integers. Also, q and s > 0 means that q*s > 0 Thus a*b can be expressed as x/y where p and r are integers implies that x = p*r is an integer q and s are positive integers implies that y = q*s is a positive integer. That is, a*b is rational.
p/q * r/s = (p*r)/(q*s)
A rational number is a number which can be expressed in the form p/q where p and q are integers and p>0.If p/q and r/s are two rational numbers then(p/q)*(r/s) = (p*r)/(q*s).You may need to check that this fraction is in its lowest (simplest) form.
It is 3*(q + p)/(r + s)
Possible. int cmp; cmp= strcmp (p, q); if (cmp<0) printf ("%s < %s\n", p, q); else if (cmp>0) printf ("%s > %s\n", p, q); else printf ("%s == %s\n", p, q);
The answer is Q.
with a loop. len= strlen (s); p= s; q= s+len-1; while (p<q) { (swap) ++p; --q; }
