I am going to assume that the subject line refers to the contents of the post. This is frequently not the case, so I apologize in advance if my assumption is mistaken.
You have the values -1/2, 2, 13/4, -3, and -6, and you need to put them in order. If it helps, convert the -1/2 and the 13/4 to decimal form. Then draw a number line from -10 to +10, and place the numbers on this line. Then list the numbers in order, by reading them off the number line.
