Question

Describe how adding and subtracting mixed numbers can help you with recipes.

Answer 1

Say you have milk and coca. 8 and 9/16 of milk. 4 and 6/16 of coca. You have to mix them together. 8 and 9/16 + 4 and 6/16 = 12 and 15/16 of milk and coca.

Answer 2

Say you're making a recipe that needs 2 1/2 cups of water. But you want to make two servings, so you need to know what 2 1/2 + 2 1/2 equals. Or maybe you need a half cup of milk but you don't have enough. You need to know how much left you need so you can buy or borrow the right amount.
