The fast method (Three names, one amount): Learn the key ones: 1/2 = 50% = 0.5, 1/4 = 25% = 0.25, 1/5 = 20% = 0.2. And: 1/8 = 12.5% = 0.125, 1/10 = 10% = 0.1, 1/20 = 5% = 0.05. Percent → decimal: ÷ 100 (point 2 places left). Decimal → percent: × 100. Fraction → percent: use the unit fraction — 3/8 = 3 × 12.5% = 37.5%.
