Making Pastries (Use visual models to solve word problems involving subtraction of fractions with like and unlike denomi

The video tutorial explains how Amanda uses pastry flour for two recipes and calculates the remaining flour using visual models. Initially, Amanda has 3 and 9/12 pounds of flour. She uses 1/12 pound for the first recipe and 1 and 1/6 pounds for the second. The tutorial demonstrates how to subtract these amounts using visual models, adjusting for unlike denominators. The final calculation shows Amanda has 2 and 1/2 pounds of flour left. The lesson teaches subtraction of fractions with unlike denominators using visual aids.
