I have a question. If a classroom has a party but then 2 more classrooms of 20 each come and do the party with them then how many party things will they need more? Fyi all the classrooms have 20 in them

2 * 20 = ________ more

it equals 40

To determine the number of party things needed for the combined classrooms, we first need to find out the total number of students attending the party.

Given that each classroom has 20 students, and there are three classrooms in total, we can calculate the total number of students as follows:

Number of students per classroom = 20
Number of classrooms = 3

Total number of students = Number of students per classroom * Number of classrooms
= 20 * 3
= 60

So, there are a total of 60 students attending the party.

To calculate the number of additional party things needed, we'll need to know how many party things are already available. If you provide that information, we can calculate the additional number of party things required.
