Final answer:
To convert from teaspoons to cups, divide the number of teaspoons by 3 and then divide the tablespoons by 16.
Step-by-step explanation:
To convert from tablespoons to cups, you need to divide the number of tablespoons by 16. In this case, since Ali only has a teaspoon, we need to convert teaspoons to tablespoons first. There are 3 teaspoons in a tablespoon, so we can divide the 1/2 teaspoon by 3 to get the equivalent in tablespoons. 1/2 teaspoon ÷ 3 = 1/6 tablespoon. Then, we can convert tablespoons to cups by dividing the 1/6 tablespoon by 16. 1/6 tablespoon ÷ 16 = 1/96 cup. Therefore, Ali has 1/96 cup of sugar to use in the recipe.
