OpenStudy (calculusxy):

Try to find the greatest common factor. @trololololol

OpenStudy (anonymous):

what?

OpenStudy (anonymous):

not sure

OpenStudy (calculusxy):

To do this problem, you just have to find the greatest common factor by lining up the factors of both 25 and 40. The greatest factor (in which the two numbers have in common) will be evenly divided with both the numerator and denominator.

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

the greatest common factor is 9

OpenStudy (anonymous):

*5

OpenStudy (calculusxy):

Yes

OpenStudy (anonymous):

What is the value of 652.94952 rounded to the tenths place? 652.95 650 653 652.9

OpenStudy (calculusxy):

To do this problem, try to identify where the tenths place is.

OpenStudy (calculusxy):

If the number that is next to the tenths place is or greater than five, then round up. If the number is four or less, round down

OpenStudy (anonymous):

652.94952 ^

OpenStudy (calculusxy):

Are you sure? See the attached image for assistance.

OpenStudy (anonymous):

idk how to do that

OpenStudy (anonymous):

oh ok the 6

OpenStudy (calculusxy):

That is still the incorrect answer. Remember, since it is the tenths place, it has to be after the decimal place.

OpenStudy (anonymous):

oh ok 9

OpenStudy (calculusxy):

Correct. Now the next step is to be sure that you follow the given rule: If the number that is next to the tenths place is or greater than five, then round up. If the number is four or less, round down

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

its 4 so i have to round down

OpenStudy (calculusxy):

Yes

OpenStudy (anonymous):

what number do i have to round to the nearest tho

OpenStudy (anonymous):

nvm

OpenStudy (calculusxy):

So what did you get?

OpenStudy (anonymous):

84952

OpenStudy (calculusxy):

I could not seem to get you.

OpenStudy (anonymous):

idk

OpenStudy (anonymous):

652.95

OpenStudy (calculusxy):

Are you sure? You were supposed to round down. But you have to round down to the tenths.

OpenStudy (anonymous):

652.9

OpenStudy (calculusxy):

Correct!

OpenStudy (anonymous):

Five of Ethan's family members went on a 6 and one-fourth hour road trip. If they all shared the drive time equally, how many hours did each family member drive? four-fifths 1 and one-fourth seven-eighths 1 and three-twentieths

OpenStudy (calculusxy):

Use keywords to find out what computation you are to use.

OpenStudy (anonymous):

five equally hours

OpenStudy (calculusxy):

Yes.

OpenStudy (calculusxy):

So what computation are you to use?

OpenStudy (anonymous):

multiplication

OpenStudy (anonymous):

i got 7/8

OpenStudy (calculusxy):

Are you sure? Since the problem stated that each of the 5 family members drove equally six and one-fourth miles and it was asked that you are to find how many miles did each person drive, what do you think?

OpenStudy (anonymous):

1 1/4

OpenStudy (calculusxy):

Correct!

OpenStudy (calculusxy):

I have to go now. Sorry.
