There are 20 teachers and 705 students in Corey's school. What is the ratio of teachers to students?
Given,
The totall Numbers of teachers = 20 and the totall number of students = 705
Thus,
The ratio of teachers to students = `"Teachers"/"Students"`
= `20/705`, = 20:705 =
`20/5`:`705/5` [dividing each side by 5]
= 4:141
Thus, the ratio of teachers to students is 4:141.
