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

If three pieces is 1/4 of the pizza, then you would multiply that by four to find the total number of pieces.

To find out how many pieces the pizza was cut into, you can use a simple equation:

3 pieces = 1/4 of the pizza

Let's solve for the total number of pieces by multiplying both sides of the equation by 4:

4 * 3 pieces = 4 * 1/4 of the pizza
12 pieces = 1 whole pizza

Therefore, the pizza was cut into 12 pieces.

To find out how many pieces the pizza was cut into, we can use some simple math. Roberto ate 3 pieces of the pizza, which is equivalent to 1/4 of the total pizza. So, we need to find a number that, when divided by 4, equals 3.

Let's set up an equation to solve this:

Number of pieces / 4 = 3

To isolate the variable "Number of pieces," we can multiply both sides of the equation by 4:

(Number of pieces / 4) * 4 = 3 * 4
Number of pieces = 12

Therefore, the pizza was cut into 12 pieces.
