Final answer:

To convert 3/8 cup to teaspoons, first convert the cups to tablespoons, then tablespoons to teaspoons, resulting in 18 teaspoons, which is answer E.

Explanation:

The student asks how many teaspoons are equal to 3/8 cup when 3 teaspoons = 1 tablespoon and 4 tablespoons = 1/4 cup. To determine the answer, we need to find the number of teaspoons in 3/8 cup by first converting cups to tablespoons and then to teaspoons.

Since 1 cup equals 16 tablespoons (4 times the 4 tablespoons in 1/4 cup), then 3/8 cup equals 3/8 times 16 tablespoons, which is 6 tablespoons. Knowing that 1 tablespoon equals 3 teaspoons, we can then multiply 6 tablespoons by 3 to find the number of teaspoons.

6 tablespoons * 3 teaspoons/tablespoon = 18 teaspoons. Therefore, the correct answer is E. 18 teaspoons.

Answer:

E. 18.

Step-by-step explanation:

4 tablespoons = 3*4 = 12 teaspoons

= 1/4 cup.

So 1/8 of a cup = 1/2 * 12 = 6 teaspoons.

3/8 of a cup = 1/4 + 1/8 = 12 + 6

= 18 teaspoons.
