Answer:
Yes, they both have same rate
Rate of A = Rate of B= 5/12
Step-by-step explanation:
Classroom A has 25 printers for 60 computers.
The rate of printers to computers is
Rate = printer /computer
Rate = 25/60
Rate= 5/12
For class room B
Classroom B has 5 printers to 12 computers
The rate of printers to computers is
Rate = printer/computer
Rate= 5/12
Rate of classroom A = 5/12
Rate if classroom B = 5/12
Rate of A = Rate of B
