Question

i have this math problem im stuck they want to know how many hours she exercise the hours are 1/4, 1/2, 1 and 1/4, 0, 2 and 1/4 whats the answer

Answer 1

1/4 hour= 1/4x60 = 15 minutes.
1/2 hour= 1/2x60 = 30 minutes.
1 hour = 1x60 minutes = 60 minutes.
1/4 hour = 15 minutes.
0 hour= 0 minutes.
2hours= 120 minutes.
1/4 hours= 15 minutes.
Adding them all in minutes: 255 minutes.
To find the time in hours, just divide by 60 because 60 minutes gives us 1 hour.
So, 255/60 hours = 17/4 hours. is the answer.

Answer 2

Just add the hours: 3/4 + 1/2 +3 hours
3 5/4
4 1/4 hours
