Understanding Percentages with Gis

In this video, Gis explains how to calculate percentages using real-life examples. The tutorial covers calculating a 20% discount on a game, finding 12% of repeated Pokémon cards, and determining 15% of a cycling distance. Gis demonstrates two methods for percentage calculations: dividing by 100 and multiplying, and directly multiplying and then dividing by 100. The video emphasizes understanding the concept of percentages and offers practical applications.
