Please help ill give medals..... Kelsey painted one-fourth of her bedroom in three-sevenths of an hour. At this rate, how long would it take her to paint the entire room?

OpenStudy (horsegal244):

@Hero @Michele_Laino

OpenStudy (anonymous):

3 hrs

OpenStudy (studygurl14):

Multiply three-sevenths by 4 to find how long it would take to paint 4/4, or the whole, room

OpenStudy (horsegal244):

12/7

OpenStudy (horsegal244):

@StudyGurl14

OpenStudy (studygurl14):

yep

OpenStudy (studygurl14):

12/7 of an hour, which is how many minutes?

OpenStudy (horsegal244):

Is that the answer?

OpenStudy (horsegal244):

1 4/7

OpenStudy (durply):

no she has already done 1/4 so it would be 9/7

OpenStudy (horsegal244):

Huh i don't get it

OpenStudy (durply):

add 3/7 3 times

OpenStudy (studygurl14):

yes, but multiply 1 4/7 by 60 to find total minutes. And @Durphy we are trying to find how long it would take to do the whole room, not how much longer it will take to finsih

OpenStudy (studygurl14):

@Durply

OpenStudy (durply):

OpenStudy (horsegal244):

OpenStudy (horsegal244):

@StudyGurl14

OpenStudy (horsegal244):

OpenStudy (horsegal244):
