Georgie needs 3 avocados to make her grandmother's guacamole recipe. If she already had 5 avocados and her sister buys another 4 avocados, how many servings of guacamole can Georgie make?
Altogether, Georgie has 5 + 4 = <T>add(5, 4)=9 avocados.
She can make 9/3 = <T>divide(9, 3)=3.0 servings of guacamole.
