Answer 1

Penjelasan dengan langkah-langkah:

a)Pechan = 2/5

Desimal = 2/5 . 2/2 = 4/10 = 0,4

Persen = 2/5 . 20/20 = 40/100 = 40%

Permil(Per Seribu ) = 2/5 . 200/200 = 400/1000= 400permil

b)Pechan =42/100 = 21/50

Desimal = 0,42

Persen = 42/100 = 42%

Permil (Per Seibu) = 42/100 . 10/10 = 420/1000 = 420 permil

c)Pechan = 72/100 = 36/50 = 18/25

Desimal = 72/100 = 0,72

Persen = 72%

Permil (Per Seibu) = 72/100 . 10/10 = 720/1000 = 720permil

e)Pechan = 13/20

Desimal = 13/20 . 5/5 = 65/100 = 0,65

Persen = 13/20 . 5/5 = 65/100 = 65%

Permil (Per Seibu) = 13/20 . 50/50 = 650/1000 = 650 permil

d)Pechan =18,75/100

Desimal = 18,75/100 = 0,1875

Persen = 18 3/4% = 18,75%

Permil (Per Seibu) = 18,75/100 . 10/10 = 187,5/1000 = 187,5permil
