Kyra exercises at a gym for 1 2/3 hours. she stretches,lifts weights, runs, and showers. kyra spends 1/4 hour stretching 1/3 hour showering.how much time does kyra spend running?
Total time (1 2/3 hours) minus the time spent stretching (1/4 hour) minus the time spent showering (1/3 hour) equals the time spent running.
x= time spent running
x= 1 2/3 - (1/4 + 1/3) change 1 2/3 to improper fraction x= 5/3 - (1/4 + 1/3) need to multiply by a common factor 3 and 4 go into 12 evenly 5/3= 20/12 1/4= 3/12 1/3= 4/12
x= 20/12 - (3/12 + 4/12) x= 20/12 - 7/12 x= 13/12 change back to mixed fraction
