There are 24 sixth graders and 47th graders mr. chan wants to divide both grades into groups of equal size with the greatest possible number of students in each group how many students should be in each group

8 students.

Step-by-step explanation:

We have been given that there are 24 sixth graders and 40 7th graders. We are asked to find the greatest possible number of students in each group having equal size.

To solve our given problem, we will find greatest common factor of 24 and 40.

Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24.

Factors of 40: 1, 2, 4, 5, 8, 10, 20, 40.

We can see that greatest common factor of 24 and 40 is 8, therefore, there would be 8 students in each group.

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.

i think 1: 2
