One classroom has 25 printers for 60 computers. Another classroom has 5 printers for 12 computers, is the rate of printers to computers the same for each classroom?

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
