Understanding Fractions and Simplification

The video tutorial explains how to determine the fraction of a grid that is shaded in pink. It starts by identifying the total number of sections in the grid and counting the shaded ones. The fraction 6/15 is derived and then simplified to 2/5 by finding the greatest common factor. The tutorial uses visual aids to demonstrate equivalent fractions and concludes by showing that 2/5 is the simplest form of the fraction representing the shaded area.
