This document discusses different strategies for solving percentage problems: the 10% rule, which involves moving the decimal place left one spot to find 10% of a number; percent proportion, which sets up a fraction to solve for a percentage amount; percent equation, which uses the percentage, whole, and part in an equation; percent of change equation, which calculates change as new amount minus old amount divided by the old amount; and tic-tac-toe table, which lays out the whole, change, percentage, and result in a table. Examples are provided for each strategy to demonstrate how to use them to solve percentage problems.
