a. how much time does carl spend dog walking every day?
b. how much time does carl spend dog walking in a week?
c. ten minutes is equal to 1/6 of an hour . how many minutes does carl work dog walking each week.

i originally posted the 1st part of the question not realizing there was multiple questions for 1 problem. any is appreciated

A)   Each day, Carl spends 1/3 of an hour walking the dog in the morning and 1/2 an hour in the afternoon. To work out how long he walks them for a day, we need to add together the two fractions.
The lowest common multiple of 3 and 2 is 6, therefore we turn the denominators into 6
From 3 to 6, we multiply by 2, therefore we do the same to the numerator
1/3 = 2/6
From 2 to 6, we multiply by 3, therefore we do the same to the numerator
1/2 = 3/6
Now we can add the numerators
2/6 + 3/6 = 5/6
5/6 x 60mins = 50 minutes per day

B)  If Carl walks the dog every day, we multiply 5/6 by 7 to find the number of hours
5/6 x 7 = 35/6 = 5 5/6 hours or 5 hours 50 minutes

C)  To convert into minutes we multiply 5 5/6 by 60
5 5/6 x 60 = 350 minutes
