Question

How do I rewrite a LINE PLOT with only the common denominators with 6, 6 1/8, 6 1/7 x 2, 6 3/8, 6 1/2, 6 5/8 x 3, 6 3/4, 6 2/8 x 2 and 7 on it?

Answer 1

56 is the LCD for all fractions, so since the values range from 6 to 7, you draw a line representing the range 6 to 7, and subdivide the line into 56 subdivisions. If the line is 5.6 inches long, one tenth of an inch (0.1") represents the subdivision. Now convert each fraction: 1/7 is represented by 5.6/7=0.8"; 1/8 is represented by 5.6/8=0.7"; 3/8=2.1"; 1/2=2.8"; 5/8=3.5"; 3/4=6/8=4.2"; 2/8=1/4=1.4". Having marked and labelled these points and the end points at 6 and 7, you complete the line plot by writing on the frequencies as crosses stacked over the relevant marks. The line plot gives a pictorial representation of your data, and you can make comparisons from this picture.
