Answer:
a) 18 students per teacher
b) 9 students per tutor
c) 7 tutors
Step-by-step explanation:
An arts academy requires there to be 6 teachers for every 108 students and 5 tutors for every 45 students.
a) How many students does the academy have per teacher?
6 teachers = 108 students
1 teacher = x
Cross Multiply.
6x = 108
x = 108/6
x = 18 students per teacher
b) Per tutor?
5 tutor = 45 students
1 tutor = x
Cross Multiply
5x = 45
x = 45/5
x = 9 students
= 9 students per tutor
c) How many tutors does the academy need if it has 63 students?
45 students = 5 tutors
63 students = x
Cross Multiply
45x = 63 × 5
x = 63 × 5/45
x = 7 tutors
(4/9) divided by (2/3) is 2/3 because you do the reciprocal and mul. Then you mult it by the reciprocal of (5/6) which is (6/5) and get 4/5
C A B is the total answer by abcd order.
The answer is 2.
3/x = 18/12
3/2 = 1 1/2
18/12= 1 1/2
The answer is 2.
