Equal groups are illustrations of using the same variable.

A word problem that uses equal group is:

Christopher traveled a distance of 5 miles yesterday; he traveled a distance of 4 miles earlier today. Calculate the total distance traveled

The only condition for equal groups is that:

The units or variable must be the same

For instance:

  • Add 5 miles and 4 miles ----- This represents distance
  • Remove 2 liters from 7 liters --- This represents volume
  • Add 5 hours and quarter of an hour -- This represents time
  • And so on.
