Example of Locating , rac{3}{4}, -rac{1}{4}, , rac{6}{5}, -rac{5}{2}, and rac{7}{3} on a Number Line
To plot these numbers accurately on a number line, place them step-by-step according to their mathematical form. Begin with the integers: and are plotted directly on their labeled integer marks. Next, locate the proper fractions: the fraction rac{3}{4} sits between and , so the interval is divided into four equal sections and marked at the third point. The negative proper fraction -rac{1}{4} is located between and , marked at the first interval to the left of zero. Lastly, convert the improper fractions into mixed numbers to easily pinpoint their placement: rac{6}{5} = 1rac{1}{5}, which is marked just past ; -rac{5}{2} = -2rac{1}{2}, placed perfectly halfway between and ; and rac{7}{3} = 2rac{1}{3}, placed one-third of the total distance passing toward .
