Ronald buys a pizza cut into 12 equal parts. He then cuts each part into 2 equal pieces. If he eats 3 of these pieces, what fraction of the pizza does he eat?
(A) $\frac{1}{24}$
(B) $\frac{1}{2}$
(C) $\frac{3}{8}$
(D) $\frac{1}{6}$
(E) $\frac{1}{8}$
Once each of 12 equal parts is cut into 2 equal pieces, there are $12 \times 2=24$ equal pieces of pizza. Ronald eats 3 of these 24 equal pieces.

Therefore, Ronald eats $\frac{3}{24}$ or $\frac{1}{8}$ of the pizza.

ANswer: (E)
