1. 2/5 × 100 = 40%
=(2×100)÷5
=200÷5
=40%
2. 3/4 × 100 = 75%
=(3×100)÷4
=300÷4
=75%
3. 2/10 × 100 = 20%
=(2×100)÷10
=200÷10
=20%
4. 9/15 × 100 = 60%
=(9×100)÷15
=900÷15
=60%
5. 7/8 × 100 = 87,5%
6. 12/15 × 100 = 80%
7. 13/14 × 100 = 92,9%
8.12/30 × 100 = 40%
9. 19/130 × 100 = 14,7%
10. 17/18 × 100 = 94,4%

14. 38/60 × 100 = 63,3%
15. 34/36 × 100 = 94,4%
*cara pertama:
%={pembilang (angka atas pecahan)×100%}÷penyebut (angka bawah pecahan)
*cara kedua:
%={100%÷penyebut(angka bawah pecahan)}×pembilang (angka atas pecahan)
note. jika 100 bisa di bagi penyebut
