Roberto ate 3 pieces of pizza and then felt that he should pay 1/4 of the costs because that's the fraction be ate. How many pieces was the pizza cut into?

12

just visualize the 3 pieces coming from 1/4 of the pizza.

wouldn't 1/2 of the pizza then be 6 slices?
Now how many slices were in the whole pizza?

john and maria had a pizza 8 slices john ate 1/3 and maria 1/4 who ate the most

To find out how many pieces the pizza was cut into, we need to use the information given.

First, we know that Roberto ate 3 pieces out of the total number of pieces. Let's represent the total number of pieces with the variable "x".

Next, we are told that Roberto believes he should pay 1/4 of the cost, which means he thinks he ate 1/4 of the pizza. Since he ate 3 pieces, we can set up the equation:

3 = (1/4) * x

To solve for x, we can multiply both sides of the equation by 4:

4 * 3 = x

12 = x

Therefore, the pizza was cut into 12 pieces.
