Jennifer is going to clean up her room. If her work rate of this job is 5/7 per hour, how long will it take her to clean her room? Your answer is supposed to have the form h hour and m minutes, where h and m are positive integers. Put h in the 1st box with the unit hr, and put m in the 2nd box with the unit min.
\n" ); document.write( "
\n" ); document.write( "Let \"x\" be the number of hours it takes her to clean her room.
\n" ); document.write( "Her rate multiplied by the amount of time to finish the job = 1 job done
\n" ); document.write( "By the way her rate means (5 jobs/ 7 hrs) or (5/7)job/hr.
\n" ); document.write( "EQUATION:
\n" ); document.write( " rate*time = job
\n" ); document.write( " [(5/7)job/hr][x hr] = 1job
\n" ); document.write( " Multiply both side by 7/5 to get
\n" ); document.write( " x = (7/5) hrs.
\n" ); document.write( "(7/5) (60 minutes) = 84 minutes = 1 hr. and 24 minutes
