  2. Bar / Line / Pie Graphs Let’s start out with the Circle or Pie Graph. These are great ways to represent relative sizes of the all the parts to the whole. Usually used to display percentages. Reed’s Family Budget Transportation 17 % 34 % Other Housing 16 % Food 10 % 23 % Entertainment

  3. Bar / Line / Pie Graphs Let’s start out with the Circle or Pie Graph. These are great ways to represent relative sizes of the all the parts to the whole. Usually used to display percentages. Reed’s Family Budget If Mr. Reed’s take - home pay = $3200 / month , we could figure out how much money the family spends on each part of the pie graph. Transportation 17 % 34 % Other Housing 16 % Food 10 % 23 % Entertainment

  4. Bar / Line / Pie Graphs Let’s start out with the Circle or Pie Graph. These are great ways to represent relative sizes of the all the parts to the whole. Usually used to display percentages. Reed’s Family Budget If Mr. Reed’s take - home pay = $3200 / month , we could figure out how much money the family spends on each part of the pie graph. Just multiply the $3200 by each percentage ( you’ll have to change the percent to a decimal ) Transportation 17 % 34 % Other Housing 16 % Food 10 % 23 % Entertainment
