Sagot :

Answer: 5 : 8 = 20 : 32

Step-by-step explanation:         5 : 8 = N : 32

Step 1 : Identify the means and extremes- means:  8, N  extremes:  5, 32

Step 2: Multiply the means:   8 x N = 8N

Step 3: Multiply the extremes:   5 x 32 = 160

Step 4: Equate the means and extremes:   8N = 160

Step 5: Solve for the missing term:   8N = 160   160 ÷ 8 = 20

                                                              8       8

N = 20
