This math topic explores the skill of calculating percent change when a number decreases. The problems specifically focus on scenarios where the decrease occurs in multiples of 10%. Each question presents a different scenario where a number shrinks to a lesser value, and the task is to determine the percentage change correctly from multiple-choice options. These problems are ideal for practicing percentage calculations in a context where numbers are reduced, helping learners understand how to effectively compute percentage differences from original values.
