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 subtracting these amounts using visual models, converting fractions to have a common denominator, and concludes that Amanda has 2 and 1/2 pounds of flour left. The lesson focuses on subtracting fractions with unlike denominators using visual aids.
