In this item, we are given with the amounts of both the flour and sugar.
Part A: First, we determine the total amount of recipes needed for the batch. total amount = (4 1/5 cup) + (2 3/7 cup) total amount = 232/35 cup
To determine the total amount of sugar needed for 4/9 of the recipe, we multiply the given amount of sugar by 4/9. That is, amount of sugar = (4/9)(2 3/7) <em> amount of sugar = 68/63 cups of sugar</em>
Part B: To determine the amount of flour needed is 3 times the given amount for each batch.
amount of flour = (3)(4 1/5 cups of flour) <em> amount of flour = 63/5 cups or 12.6 cups of flour</em>
