The ratio of two integers P and Q can be expressed as P : Q or P/Q. In both cases, you may divided P and Q by their greatest common factor so as to express the ratio in its simplest form.
9) The sum of two rational numbers is rational: Proof: Let r and w be two rational numbers. By definition of rational. acr and wbd == where a,b,c,d are integers and bâ 0 and dâ 0 Consider a c ad bcrwbd bd ++=+= where bd â  0 is an integer and ad +bc is an integer. Therefore the sum is rational by definition. 10) The product of two rational numbers is rational. Proof: Let r and w be two rational numbers. By definition of rational acr and wbd == where a,b,c,d are integers and bâ 0 and dâ 0 Consider * ac acrwbd bd == where bd â  0 is an integer and ac is an integer.
