20 % = 20/100 = 1/5
35 % = 35/100 = 7/20
76 % = 76/100 = 19/25
2,5 % = 2,5/100 = 1/40
33 1/3% = 100/3 % = 100/300 = 1/3
71 3/7% = 500/7 % = 500/700 = 5/7
5/100 × Rp 80.000 = 4.000
12,5/100 × 40 = 5 kg
20% = 20/100 = 1/5
35% = 35/100 = 7/20
76% = 76/100 = 19/25
2,5% = 2,5/100 = 1/40
33,33% = 33,33/100 = 1/3
