Respuesta :

Answer: Pizza and tacos will be served on the

same day again in 12 school days.

Step-by-step explanation:

Hi, to solve this we have to analyze the information given:

  • Pizza: served every fourth day
  • Tacos: served every third day

To calculate in how many days pizza and tacos will be served on the same day again we have to find the least common multiple of 4 (pizza) and 3 (tacos).

Mathematically speaking:

4 :4,8,12

3:3,6,9,12

So, the least common multiple of 4 and 3 is 12.

Pizza and tacos will be served on the

same day again in 12 school days.
