In a certain theater, there are 16 empty seats out of 240 total seats. write a ratio of empty seats to total seats as a fraction in simplest form. then explain

Step-by-step explanation:

Number of empty seats = 16

Total number of seats = 240

To find : ratio of empty seats to total number of seats as a fraction in simplest form.

A fraction is said to be in simplest form if

Solution:

ratio of empty seats to total number of seats = Number of empty seats / Total number of seats =

Here, is not in simplest form , so we need to solve it further .

We know that HCF is greatest common factor , so

Therefore,

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.
