There are 321 visitors at the library. Each library table seats 12 people. How many tables are needed to seat all of the visitors?

(Explain the process of how you got your answers)

Hello.

The answer is: 27

To get this answer you can divide 321 and 12. But that will give you an uneven number such as 26.75. And because you cant have 26.7 tables you will wound it up to be 27 tables.

321:12=26.75

answer: 27

Step-by-step explanation:

since you know that each table can only seat 12 people and there is 321 visitors you divide 321 by 12 which you get 26.75, but u cant have 26.75 tables so you round up to 27 so you can seat all the visitors because if you round down to 26, 9 people won't have a seat.
