19. 4/6 or 2/3 (lowest term) or 2:3 in ratio
20. 2/3 or 2:3 in ratio
21. 5/12 or 5:12 in ratio
22. 14
    To get geometric mean, multiply the numbers then get the square root of the product (if there are two numbers), cube root (if there are three numbers), and so on. In this case, 7*28 = 196; √196 = 14
23. 10 ft : 2.5 ft.
    Convert the values so that it will be similar. In this case, 30 inches is converted to ft.
24. 24 is the Perimeter of ABCDE.
    ABCDE and FGHJK are similar shapes. Similar shapes have proportional measurements.

Now compute for the sides of ABCDE.
AB = 4; BC = ?; CD = ?; DE = ?; EA = ?
AB + BC + CD + DE + EA
4 + 4 + 5 + 6 + 5 = 24

Find BC:
AB/BC = FG/GH
   4/BC = 8/8 
    8BC = 32
      BC = 4

Find CD:
BC/CD = GH/HJ
   4/CD = 8/10
    8CD = 40
      CD = 5

Find DE:
CD/DE = HJ/JK
   5/DE = 10/12
  10DE = 60
       DE = 6

Find EA
DE/EA = JK/KF
   6/EA = 12/10
  12EA = 60
      EA = 5

and so on. so you write and solve

9.30(1), 9.30(5), 9.30(8)

for the second part you want to substitute 180 for the amount earned which will become

melomori [17]

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.
