Person 1 practices the piano for 25 minutes every day, while Person 2 practices the piano for a total of 140 minutes per week. To compare these proportional relationships, we need to find out how many minutes Person 2 practices per day.
Since there are 7 days in a week, we divide 140 by 7 to find out the number of minutes Person 2 practices per day: 140 รท 7 = <<140/7=20>>20.
Therefore, Person 2 practices 20 minutes per day, which is less than the 25 minutes Person 1 practices. So, Person 2 practices less per day.
