Description: We hope you learn to cook. Everyone should! At some point you'll need to make 1/2 a recipe which means using 1/2 of every ingredient in the recipe. Here's an example. A recipe for banana oat muffins calls for 3/4 of a cup of old-fashioned oats. So if the whole recipe requires 3/4 of a cup and you're making half of the recipe, you want half of 3/4, right? You want half of the number of old-fashioned oats as the whole recipe.*Teacher Advisor is 100% free.
