OpenStudy (moazzam07):

Which school has the greatest percentage of students who like sandwiches for lunch? School A School B School C School D

OpenStudy (anonymous):

ok ill walk you through this

OpenStudy (moazzam07):

ok

OpenStudy (anonymous):

So in school A, 12/38 students like sandwiches. List the same thing for the rest of the schools.

OpenStudy (moazzam07):

ok

OpenStudy (moazzam07):

school b is 9/48

OpenStudy (moazzam07):

school c is 10/26

OpenStudy (moazzam07):

and School d is 8/24

OpenStudy (anonymous):

so all these fractions have to be converted to percentages. you know how to do that?

OpenStudy (moazzam07):

yeah mate

OpenStudy (anonymous):

ok i will do school A and B and you do C and D ok?

OpenStudy (moazzam07):

ok

OpenStudy (moazzam07):

i got 3 for D

OpenStudy (anonymous):

School A is 32% School B is 19%

OpenStudy (moazzam07):

ok how you do that

OpenStudy (moazzam07):

i got whole numbers

OpenStudy (anonymous):

lol ok so you divide the top number by the bottom number of the fraction. you can use a calculator.

OpenStudy (anonymous):

so since A is 12/38, i divided 12 by 38 and i got 0.315789

OpenStudy (anonymous):

i moved the decimal which is this>> . two spaces to the right. so it landed right after the 1. your number is now 31.5789 but we cant use that. so we round up?

OpenStudy (anonymous):

you know how to round?

OpenStudy (anonymous):

so i rounded that up to 32. so i got 32%. get it?

OpenStudy (moazzam07):

ah i get it thanks man
