Tom and jose entered a pie eating contest of the
fair. tom came in first place eating 8/9 of a pie. jose took third place eating 2/3 of a pie. who ate more? how much more?

who ate more?
how much more?

Tom; 2/9 more

Step-by-step explanation:

To compare fractions, they need to have a common denominator. We get this by multiplying the fractions least common multiple of the denominators. So:

the LCM of 9 and 3 is 9.

Multiply 2/3 by 3/3 to get 6/9

8/9 already has 9 as a denominator

8/9 is more than 6/9, so Tom ate more. 8-6 is 2, so he ate 2/9 of a pie more.

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.

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.
