Answer:
12 cleaners
Step-by-step explanation:
8 cleaner can clean in 3 hours = 1 office
1 cleaner can clean in 3 hours =
part of job
1 cleaner can clean in 1 hours =
part of job

x cleaner can clean in 1 hours =
part of job
x cleaner can clean in 2 hours =

750 total students
To find the number of boys you take 420/56. This would tell you the number of students per 1 percent. This would give 7.5 people per 1 percent. Then tale 7.5 times the remaining 44% and that would equal 330 boys in the school. Add boys plus girls and that would get you the 750 total students.
