This math topic focuses on calculating the percent change when a number decreases (shrinks). It hones in on the skill of identifying how much smaller a number becomes when reduced by a certain percentage. The problems present a starting value that shrinks to a lesser value, and the learner is tasked with determining the percentage decrease between these two values. This topic is part of an advanced study on percentages and teaches learners to accurately calculate and understand percentage decreases in various contexts.
