a. How much flour and how much yeast do you need for two batches of bread? Draw a picture that shows the batches as well as the total amount of flour and total amount of yeast needed. b. How many batches can you make with 15 cups of flour and 6 teaspoons of yeast? Indicate the batches in the picture. c. We say that the ratios 5:2, 10:4, and 15:6 are equivalent. In this case, even though the amounts of each ingredient are not the same, they would make the same kind of bread. Find another ratio equivalent to these (and that would correspond to the same kind of bread) and draw a picture to represent it.
