1. 30%, 2. 175%, 3. 40%

Pembahasan

Untuk mengubah pecahan menjadi persen, kita kalikan pecahan tersebut dengan 100%.

1. 15/50 = (15/50) * 100% = 15 * (100/50)% = 15 * 2% = 30%
2. 7/4 = (7/4) * 100% = 7 * (100/4)% = 7 * 25% = 175%
3. 8/20 = (8/20) * 100% = 8 * (100/20)% = 8 * 5% = 40%

Jadi:
1. 15/50 = 30%
2. 7/4 = 175%
3. 8/20 = 40%
