a large pizza has 12 slices. bobby ate 1/4 of pizza, how many slices of pizza did he eat?

What Bobby Ate = 1/4(Pizza)

Pizza = 12 slices,

So, What Bobby Ate = 1/4(12 slices),

Therefore, What Bobby Ate = 1/4(12 slices) = 3 slices

...

Check your answer: The pizza slices can be written as 3 + 3 + 3 + 3 = 12 ... There are 4 sets slices, with 3 slices per set... The problem states that Bobby ate 1/4 of the pizza... One fourth of the pizza is one set, and one set is 3. So, Bobby ate 3 slices.
