Relate Ratio Tables to Graphs


Work Time


Ms. Lopez also sells biscuits in packages.

She uses this ratio table to determine the number of packages she will need for different numbers of biscuits.

  • Complete the ratio table.
  • Make a graph that shows the information in the ratio table.
  • Use the ratio table to find the number of biscuits that will fill 39 packages.

Ask yourself:

  • The second column of the ratio table (with a 1 in the top cell) tells you the number of biscuits in 1 package.
  • Each pair of numbers in the columns of the ratio table represents an ordered pair that defines the coordinates of a point on the graph.
  • How could you add to or subtract from numbers in the table to find the number of biscuits in 39 packages?
