Greata had a price of cloth that is 9 yards long. She cuts it into prices that are each 1/3 yard long. How many prices of cloth does Greata have now?

Given:

Length of cloth = 9 yards

Length of pieces = yards each

To find:

The number of pieces of cloths after cutting.

Solution:

Let n be the number of required pieces.

Length of each piece is yards. So, the length of n pieces is yards.

The length of the whole cloth is 9 yards. So, yards must be equal to 9 yards.

Multiply both sides by 3.

Therefore, the Greata have 27 pieces of cloths.

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.
