use recipes to practice multiplication with fractions and mixed numbers work together to solve problems such as one batch of recipe calls for 2 1/4 cup of flour how much would flour would we need to make 1/2 batches
1 batch uses 2.25 cups, so a 1/2 batch would use half the cups of flour as a full batch the proportion would be 1/2.25=0.5/x cross multiply (1*x)=x (2.25x0.5)=1.125 x=1.125
