Where is the expression in the answer it would be helpful
Min needs exactly 1.75 meters of ribbon to make all 100 name tags.
Kris:
4.37 hours per day for 3 days.
To find the total practice time, multiply the practice time per day by the number of days.
4.37 • 3 = 13.11
This means Kris practiced for 13.11 hours.
Amelia:
6.39 hours per day for 4 days.
To find the total practice time, multiply the practice time per day by the number of days.
6.39 • 4 = 25.56
This means Amelia practiced for 25.56 hours.
To find the difference, just subtract Kris's practice time from Amelia's practice time.
25.56 - 13.11 = 12.45
This means Amelia practiced for 12.45 more hours than Kris.
