10. two thirds of mrs. auten's advisory class
brought their attendance contracts back on
tuesday. if her advisory class has 30 students,
how many brought their attendance contracts
back on tuesday?

20 students

Step-by-step explanation:

In order to find the answer, we must find 2/3 of 30 students.

2/3 of 30 students can be found by multiplying the two numbers together.

2/3 * 30 is equal to 2/3 * 30/1

2/3 * 30/1 is 60/3

60/3 is equal to 20

20 students brought their attendance contracts back on Tuesday.

could you reply to this with the question so i can ?
