Final answer:
The total quantity of spices needed for the recipe, when converted to teaspoons, is 1 3/8 teaspoons. Conversions from tablespoons to teaspoons are necessary, and the calculated amount does not match any of the answer choices given.
Step-by-step explanation:
The total quantity of spices in the recipe is determined by converting all measurements to the same unit and then adding them together. In this case, we will convert tablespoons to teaspoons to calculate the total quantity, as the recipe involves measurements in both teaspoons and tablespoons.
- 1/4 teaspoon of turmeric is already in teaspoons.
- 1/8 tablespoon of ginger needs to be converted to teaspoons. There are 3 teaspoons in a tablespoon, so 1/8 tablespoon is equivalent to 3/8 teaspoon.
- 1/4 tablespoon of cumin also needs to be converted to teaspoons. Therefore, 1/4 tablespoon is equivalent to 3/4 teaspoon.
We add the quantities together: 1/4 teaspoon (turmeric) + 3/8 teaspoon (ginger) + 3/4 teaspoon (cumin) = 1/4 + 3/8 + 3/4 = 2/8 + 3/8 + 6/8 = 11/8 teaspoons. Dividing 11 by 8 gives us 1 3/8 teaspoons, which is the total quantity of the spices needed for the recipe.
Note that none of the answer choices match the calculated amount, so there seems to be an error in the options provided to the student.
