Terrence normally uses one-fourth teaspoon of dried basil to make his own salad dressing. He decides to change the recipe and include extra dried basil. He decides that the flavor is perfect when including a total of five-eighths teaspoon.
Write an addition equation that could be used to determine the additional amount of basil, b, Terrence added. Solve for b. Describe your steps.
(1/4) + b = 5/8
b = (5/8) - (2/8)
b = 3/8
