Under this plan, the reduced rates apply to what fraction of a week?
Reduced rates apply to the fraction of the week is = Total hours at reduced rate / Total hours in the week
Reduced rates apply to the fraction of the week is = (60+48) / (24*7)
Reduced rates apply to the fraction of the week is = 108 / (24*7) => = 9/14
