Need help with this word problem

[Deanna]

• Dale really likes his job; he works three 12-hour days per week. He spends 1/2 of his time on building inspection and maintenance and 1/3 of his time on machine inspection and maintenance. He also spends 2 and 3/4 hours per week analyzing all production rates. If he works 49 weeks per year, how many total hours does he have left in the year for other duties?

i) how many hrs per week does Dale work?
ii) how many hrs a week is 1/2 of this? how many is 1/3 of this? Add these to 2 3/4 to get the hrs per week that are accounted for.
iii) how many hrs a week are unaccounted for?
iv) multiply this by how many weeks a year he works to get the total hrs per year available for other duties.
