E:
1. 3/2
2. 3/4
3. 33/100

Answer 2

Bagian D (Mengubah ke persen) :
1) 6/30 = 20%
=> 6/30 = (6 : 6)/(30 : 6) = 1/5  
=> 1/5 = (1 × 20)/(5 × 20) = 20/100 = 20%

2) 4/5 = 80%
=> 4/5 = (4 × 20)/(5 × 20) = 80/100 = 80%

3) 3/4 = 75%
=> 3/4 = (3 × 25)/(4 ×25) = 75/100 = 75%


bagian E (mengubah ke pecahan biasa) :
1) 150% = 3/2
=>150% = 150/100 = 15/10 = (15 : 5)/(10 : 5) = 3/2

2) 75% = 3/4
=> 75% = 75/100 = (75 : 25)/(100 : 25) = 3/4

3) 33% = 33/100
=> 33% = 33/100
