Ronald buys pizza cut into 12 different parts. he then cuts each part into 2 equal peices. if he eats 3 of these peices, what fraction of the pizza does he eat

Ronald's eaten 3/24 of the pizza.
If he cuts each of the 12 different parts of a pizza into 2 more pieces, he's cut 24 pieces total (12 x 2). Eating 3 of the 1/24 slices means he's eaten 3/24 of the pizza.

221,500 is the answer
