Pecahan berikut menjadi pecahan biasa:

15% = 15/100 => 15/100 ÷ 5/5 = 3/20

8% = 8/100 => 8/100 ÷ 4/4 = 2/25

50% = 50/100 => 50/100 ÷ 50/50 = 1/2

62% = 62/100 => 62/100 ÷ 2/2 = 31/50

75% = 75/100 => 75/100 ÷ 25/25 = 3/4

Pecahan berikut menjadi desimal

1/4 => 1/4 × 25/25 = 25/100 = 0,25

1/2 => 1/2 × 5/5 = 5/10 = 0,5

3/4 => 3/4 × 25/25 = 75/100 = 0,75

1/10 = 0,1

1/5 = 1/5 × 2/2 = 2/10 = 0,2

Pecahan berikut menjadi persen

1/2 => 1/2 × 50/50 = 50/100 = 50%

3/4 => 3/4 × 25/25 = 75/100 = 75%

5/100 = 5%

2/5 => 2/5 × 20/20 = 40/100 = 40%

7/10 => 7/10 × 10/10 = 70/100 = 70%

Pecahan berikut menjadi persen

0,4 = 4/10 => 4/10 × 10/10 = 40/100 = 40%

0,21 = 21/100 = 21%

0,07 = 7/100 = 7%

0,68 = 68/100 = 68%

0,6 = 6/10 => 6/10 × 10/10 = 60/100 = 60%
