Based on the ratio, 6 students play musical instruments.
The mentioned problem can be solved using the concept of ratio and proportion. We will equate the two ratio. Let us assume the number of students who play musical instruments be x.
Forming the equation -
3 : 20 = x : 40
Rewriting the equation with respect to x
x = (40 × 3) ÷ 20
Performing multiplication and division on Right Hand Side of the equation
x = 120 ÷ 20
Performing division on Right Hand Side of the equation
x = 6
Therefore, 6 students play musical instruments.

Answer:
16. D. 180 inches
17. A. 1/20 pound
18. D. (2,6)
19. A. 2/8
20. D. 22
Step-by-step explanation:
16. every 5 feet is 60 inches there is 15 feet because 1 yard=3 feet so 60*3=180
17. when you round it upwards you would have 30/40 and 32/40 so it would be 2/40 and then simply 1/20 so therefore it would be 1/20
18. The cost of milk is 3 so that would be (3,y) then every gallon would be y so (3,1)
19. You know this because when you plug in all the other numbers none of the rest of them work but A so therefore it must be A
20. So first you would multiply 2*2*2*2=8 Then you would divide 172/8=22. So therefore your answer would be 22
