Question

office opens at 9:00 a.m. and closes at 5:30 with the lunch break of 30 minutes what is the ratio of the lunch break to the total period in the office

Answer 1

office opens at 9:00 a.m. and closes at 5:30 with the lunch break of 30 minutes

so, total office in hours from 9:00 am to 5:30pm without lunch break is = 8 hours

total office in time = 8*60 = 480min

ratio of lunch break to total period of office = 30:480 = 1:16
