1. Mark practices the piano for 2/3 of an hour for 6 hours every week. How many hours does he practice each week?

4 hours each week

Step-by-step explanation:

2/3 of an hour = 40 minutes

40 times 6 = 240 minutes

240 (minutes) / 6 (hours) = 4 hours practiced each week

I hope this helps :)

if you get paid hourly because if you get a salary you could work all week and only get paid a certain amount no matter how much you work but if you get paid hourly then you get paid for every minute you worked.
