central middle school has 2470 students and the ratio of students to teachers is 26:1 how many new teachers are needed to reduce this to 19:1? Hi, To have a student to teacher ratio of 26:1, divide the students into groups of size 26. Ther are 2470 students so there are ^{2470}/_{26} = 95 groups of size 26. Each group has 1 teacher assigned so there are 95 teachers. How many teachers are required if the ratio of students to teachers is 19:1? Penny
