This math topic focuses on determining the percentage decrease for given numbers. It specifically deals with scenarios where initial numbers decrease to lower values and students must calculate the exact percent change. The changes are presented in 5% increments to simplify the computation process. The problems are structured with multiple-choice answers, encouraging learners to distinguish between different rates of decrease and select the correct percentage that represents the reduction from the original number to its new value.
