Positive rational numbers are always represented on the right side of the zero on the number line. While negative rational numbers are always represented on the left side of zero on the number line.
Divide the fraction gives you an irrational number since the decimal goes on forever but since the decimal can be written as a "fraction or ratio" it is rational.
Best of Luck!
